CAS Numbers

In order to accurately classify our Clients’ product mixtures, Dell Tech requests the raw material CAS numbers. Some clients have asked, What is a CAS Number?

A CAS Number is a unique numerical identifier assigned by the Chemical Abstracts Service (CAS), a division of the American Chemical Society,  to every unique chemical. The universally accepted number assigned can contain upwards to 10 digits. The CAS assigned to a chemical is divided by hyphens into three parts. The CAS Registry is updated daily with approximately 15000 new chemicals.  If a chemical does not have a CAS assigned, one applies to the service to obtain one.

An example of a widely known CAS Number is Formaldehyde: 50-00-0

For further information on how to obtain a CAS for a new chemical, please visit the American Chemical Society
