- It is a chemical database that includes organic and inorganic compounds, minerals, isotopes, alloys, mixtures, and nonstructurable materials.
- CAS RNs are generally serial numbers, so they do not contain any information about the structures themselves the way SMILES and InChI strings do.
Why it is Uncommon

ATK comes from the length of the article and DEF from its quality, so this card hits with 60 and blocks with 34: each hit it takes is cut by 14 %.
