Check Digit Verification of cas no

The CAS Registry Mumber 3197-57-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,9 and 7 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3197-57:
(6*3)+(5*1)+(4*9)+(3*7)+(2*5)+(1*7)=97
97 % 10 = 7
So 3197-57-7 is a valid CAS Registry Number.

Solvent free one-pot multi-component synthesis of β-azaarene substituted ketones via a Sn-catalyzed C(sp3)-H functionalization of 2-alkylazaarenes

Chavan, Santosh S.,Pathan, Mohsinkhan Y.,Mulla, Shafeek A. R.

, p. 103091 - 103094 (2015/12/23)

A tin-catalyzed solvent free one-pot multi-component cascade reaction strategy for the direct Michael addition/C(sp3)-H functionalization of 2-alkylazaarenes with aldehydes and ketones via an aldol reaction has been developed. This is the first report and provides cost effective new access to potent biologically/medicinally important azaarene derivatives with high atom economy.
