机油的CASNO是什么

废机油标签可以这样填写：拿个油桶装好后，在油桶上方，贴上长方形的白纸，上写：10号废机油。

新修订的《中华人民共和国固体废物污染环境防治法》（以下简称新固废法）已于2020年9月1日起实施。新固废法强化了政府及其有关部门监督管理责任，不仅完善了工业固体废物、生活垃圾、危险废物、建筑垃圾、农业固体废物等污染环境防治制度，还对法律责任专章进行了扩充完善，加大了对固废管理不合规的处罚力度。

并且增加了按日连续处罚、行政拘留、查封扣押等执法措施。其中新固废法对环境违法行为的“严惩重罚”方面达到了新高度，多项违法行为的罚款数额是旧固废法的10倍，特别是“未设置危险废物识别标志”这一违法法行为。旧固废法规定“不设置危险废物识别标志的”。

处1万以上10万以下的罚款。而新固废法要求比旧版固废法更加严厉，不仅需要“设置”，还应该“规范设置”危险废物识别标志，若不规范，处十万元以上一百万以下罚款！

设置要求：

（1）位置

危险废物贮存间外。

（2）设置方式

①悬挂于危废贮存间外面门的一侧，或。

②独立摆放于危废贮存间外。

下面简单说一下cas编码的组成。由六位到九位的数字组成。其一般形式为【####aa-aa-a】。其中#表示可有可无的数字，a表示必须有的数字。也就是说最前面的数字位数是不一定的，有些物质是两位，最多可达六位。然而无论是什么化合物，必需至少有五位数组成。在原则上，数字大小可以反映物质发现的早晚，数字越大，表示发现得越晚。现在已有2000万余种物质有自己的cas编号。

cas编号最早出现于美国化学摘要服务社（chemical abstracts service，CAS即为该服务社的缩写)出版的《化学摘要》，与其同时研发的网上检索系统，后来凭借无比的优越性，其他出版社也采用cas编码来标明化学物质，现在海关化学物品进出口，也要登录该资料。

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
