AI overview
A CAS Registry Number is a unique numerical identifier assigned to every chemical substance by the Chemical Abstracts Service, making it possible to clearly distinguish one chemical from another regardless of what language or naming system is used. This standardized system matters because it ensures scientists, manufacturers, and regulators worldwide can accurately reference and track specific chemicals without confusion.

CAS編號（CAS Registry Number，或称CAS Number，CAS Rn，CAS #），又称CAS登录号或CAS登記號碼，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，簡稱CAS）负责为每一种出现在文献中的物质分配一个CAS編號，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編號检索。
