CAS号查询库

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。
