22、Registry NumberEach CAS Registry Number (RN) is a unique numeric identifier that contain up to 9 digits, divided by hyphens into 3 parts. Each RN designates only one substance. It has no chemical significance and is a link to a wealth of information about a specific chemical substance. There are over 32,000,000 RNs. Searching by RN is very effective.CAS Registry Number CAS Registry Numb
