聚氨基丙烯酸酯材料的cas号

CAS码来源于美国化学会的下设组织：化学文摘社（Chemical Abstracts Service，简称CAS）。该社负责为每一种出现在文献中的物质分配一个CAS编号，这是为了避免化学物质有多种名称的麻烦，使数据库的检索更为方便。其缩写CAS在化学上便成为化合物唯一识别码的代称，相当于每一种化合物都拥有了自己的身份证。

需要注意的是，同一化合物的不同水合物/无水物拥有不同的CAS号，但与试剂的级别没有关系，CAS号可以避免采购时因一物多名而带来的不必要的麻烦，也就是说你有必要建立一个名称-CAS号对应表，在采购时对一些特殊的试剂备注上CAS号，以避免采购错误或“采购不到”。

化学试剂的分级：

通常按照国家标准的要求可以将化学试剂分为通用试剂、基准试剂和生物染色剂，而通用化学试剂分为化学纯、分析纯和优级纯，并要求其相应标签的主色调分别为中蓝色、金光红色和深绿色，基准试剂与优级纯试剂标签的颜色相同均为深绿色，生物染色剂为玫红色。

相应的，中国药典将试剂分为四种，基准试剂、化学纯、分析纯和优级纯，并明确了标定的基准物质为基准试剂，用于杂质限度检查用的标准溶液（例如氯化物、硫酸盐等），应采用优级纯或分析纯，其他检测和制备可以使用分析纯或化学纯试剂。

CAS的优势：

1，避免了因部分学校提供的信息模糊不清，导致申请签证时带来不必要的麻烦及拖延。CAS会提供给所有大学一个统一的表格，里面包含所有申请签证所需要的信息，使馆可以清晰明了地掌握，加快了审理时间。

2，以往如果在签证时发现学校签发的VisaLetter有问题，学生要再向学校申请，而CAS号可以避免这一点，学校及时在系统里做出更新以方便使馆查询。因为CAS号由英国边境管理署直接签发给学校，每个学生仅有一个号码，所有学校提供的信息或做出的更新都仅针对固定学生。

3，大学也可根据CAS号查询申请程序，更易追踪和掌握学生的动态。

CAS registry numbers are unique numerical identifiers for chemical compounds, polymers, biological sequences, mixtures and alloys. They are also referred to as CAS numbers or CAS RNs.

Chemical Abstracts Service (CAS), a division of the American Chemical Society, assigns these identifiers to every chemical that has been described in the literature. The intention is to make database searches more convenient, as chemicals often have many names. Almost all molecule databases today allow searching by CAS number.

As of Nov 2, 2005, there were 26,901,696 substances in the CAS registry — the current number is published here. About 4,000 new numbers are added each day.

CAS registry number is separated by hyphens into three parts, the first consisting of up to 6 digits, the second consisting of two digits, and the third consisting of a single digit serving as a check digit.

2。 UN no. 才是危险品特有的。 运输都要有这号码。

UN numbers or UN IDs are four-digit numbers that identify dangerous goods hazardous substances and articles (such as explosives, flammable liquids, toxic substances, etc.) in the framework of international transport. Some hazardous substances have their own UN numbers (e.g. acrylamide has UN2074), while sometimes groups of chemicals or products with similar properties receive a common UN number (e.g. flammable liquid, not otherwise specified, have UN1993). A chemical in its solid state may receive a different UN number than the liquid phase if their hazardous properties differ significantlysubstances with different levels of purity may also receive different UN numbers.

UN numbers range from UN0001 to about UN3500 and are assigned by the United Nations Committee of Experts on the Transport of Dangerous Goods. They are published as part of their Recommendations on the Transport of Dangerous Goods, also known as the Orange Book. These recommendations are adopted by the regulatory organization responsible for the different modes of transport.

NA numbers (North America), also known as DOT numbers are issued by the United States Department of Transportation and are identical to UN numbers, except that some substances without a UN number may have an NA number. These additional NA numbers use the range NA8000 - NA9999.

Associated with each UN number is a hazard identifier, which encodes the general hazard class and subdivision (and, in the case of explosives, their compatibility group). For instance, the hazard identifier of acrylamide is 6.1 and the one of cigarette lighters is 2.1. If a substances poses several dangers, then subsidiary risk identifiers may be specified. It is not possible to deduce the hazard class(es) of a substance from its UN number: they have to be looked up in a table.

The hazard classes and their divisions are:

Class 1: Explosives

Division 1.1: Substances and articles which have a mass explosion hazard

Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard

Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard

Division 1.4: Substances and articles which present no significant hazard

Division 1.5: Very insensitive substances which have a mass explosion hazard

Division 1.6: Extremely insensitive articles which do not have a mass explosion hazard

Class 2: Gases

Division 2.1: Flammable gases

Division 2.2: Non-flammable, non-toxic gases

Division 2.3: Toxic gases

Class 3: Flammable liquids

Class 4: Flammable solidssubstances liable to spontaneous combustionsubstances which, on contact with water, emit flammable gases

Division 4.1: Flammable solids, self-reactive substances and solid desensitised explosives

Division 4.2: Substances liable to spontaneous combustion

Division 4.3: Substances which in contact with water emit flammable gases

Class 5: Oxidizing substances and organic peroxides

Division 5.1: Oxidizing substances

Division 5.2: Organic peroxides

Class 6: Toxic and infectious substances

Division 6.1: Toxic substances

Division 6.2: Infectious substances

Class 7: Radioactive material

Class 8: Corrosive substances

Class 9: Miscellaneous dangerous substances and articles
