What Is a CAS Number and How Is It Assigned? - ThoughtCo
CAS Numbers are up to 10 digits long using the format xxxxxxx-yy-z. They are assigned to a compound as the CAS registers a new compound. The number has no significance to the chemistry, structure, or chemical nature of the molecule. The CAS Number of a compound is a useful way to identify a chemical over its name.

CAS_CAS号查询库【化源网】
CAS号是公开的化学物质信息的最权威的集合。 CAS号涵盖从1957年至今的科学文献中确定的物质，其他物质可追溯到20世纪初。 它也称CAS编号 (CAS Registry Number，或称CAS Number，CAS Rn，CAS #)，又称CAS登录号或CAS登记号码，是某种物质 (化合物、高分子材料、生物序列 (Biological sequences)、混合物或合金)的唯一的数字识别号码。 美国化学会的下设组织化学文摘社 (Chemical Abstracts Service，简称CAS)负责为每一种出现在文献中的物质分配一个CAS编号，其目的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。 如今几乎所有的化学数据库都允许用CAS编号检索。 上一页 1 2 3 4 5
