NOTE: Chemical Abstracts have agreed to perform this work for us. Information on this process will be posted once details are available.

This topic is the main agenda item at the February 5th IRC Meeting. Please join us!

There are two types of validation which may be done with CAS numbers. One is a mathematical validation, designed to detect mistyped CAS numbers. The other method is to validate that the number is assigned to a chemical.
