Everything you always wanted to know about CAS numbers…

CAS number, a unique identifier for your chemical compounds!


Found on all chemical compound labels, the CAS number is a unique numerical identifier. Learn more about this number that will keep surprising you.


First, the acronym CAS comes from the Chemical Abstracts Service (CAS) of the American Chemical Society (ACS) founded in 1907. The aim of this service is to produce an index of abstracts from the scientific literature, but also to maintain a CAS registry, which is also the largest database of chemical substances.



A long lasting story

Since 1907, chemical substances have been assigned a unique CA index name, a CAS number and a graphical representation of the chemical structure. This registry now contains more than 168 million organic and inorganic compounds, as well as 68 million protein sequences and nucleic acids.


The CAS number is therefore a numerical identifier for each chemical substance that can contain 10 digits separated into 3 groups by hyphens. This number has become a reference in the census of compounds thanks to its universality.



A smart way to use CAS numbers

Of course, as soon as many different chemical nomenclatures do exist, the search for a product becomes quite complex. Therefore, the CAS number offers great advantages: a simple, fast and accessible identification of the product to everyone!


And that is what makes our mobile app Ineon Safety Pro so special! Our digital solution integrates an innovative scanning functionality reading and recognizing any CAS numbers on any product label. Even if the label is so tiny that your glasses are not sharp enough.


Furthermore, the app associates each CAS number with the corresponding safety data sheet, gathering all information indicated on the label as well as all safety information and instructions. Once you’ve scanned the CAS number, the app finds instantly the fitting MSDS among more than 5000,000 registered in our databases. And of course the app is available on both Android and iOS. Couldn’t be more easy, isn’t it?
