用化学危险品un编号怎么查cas号

序号 类别 项目 危险货物编号 品名 别名 英文名 英文别名 CAS号 UN号

1 易燃液体 高闪点液体 33557 甲基环己醇 六氢甲酚 MethylcyclohexaHexahydrocresol 25639-42-3 2617

2 毒害品和感染性物品 毒害品 61112 磷酸三甲苯酯 磷酸三甲酚酯增塑剂TCP Tricresyl phosphate TritolylphosphatePlasticizer TCP 1330-78-5 2574

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

危险品包装上的UN是联合国危险货物编号。

联合国危险货物编号是一组4位数字，它们可以被用来识别有商业价值的危险物质和货物（例如爆炸物或是有毒物质）。这种数字架构在国际贸易当中被广泛使用，以便于标注货运容器的内容。

从UN0001到大约UN3500的编号都是由联合国危险物品运送专家委员会制定的。这些编号在《关于危险货物运输的建议书》中公布。协调各种运输方式的一些组织机构已经在使用这一系统。

危险货物的判别

①根据品名、CAS号，直接判断是否属于危险化学品；

② 根据安全数据单，收集货物别名、闭杯闪点或者结合GHS分类，判定是否符合「危险化学品的定义和确定原则」；

③ 根据安全数据单第十四部分运输信息中联合国UN编号，判定是否属于危险货物；

④ 根据货物外包装是否加贴运输标签（危险化学品象形图与危险货物运输标签的显著差异，见图2、图3），判定是否属于危险货物；

⑤ 根据危险特性分类鉴定报告或货物运输条件鉴定书，判定货物是否属于危险化学品或危险货物。
