Check Digit Verification of cas no

The CAS Registry Mumber 22903-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,0 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22903-40:
(7*2)+(6*2)+(5*9)+(4*0)+(3*3)+(2*4)+(1*0)=88
88 % 10 = 8
So 22903-40-8 is a valid CAS Registry Number.

Photocatalytic aerobic α-thiolation/annulation of carbonyls with mercaptobenzimidazoles

Ji, Xiaochen,Tan, Muyun,Fu, Mei,Deng, Guo-Jun,Huang, Huawen

, p. 4979 - 4983 (2019)

A concise aerobic photocatalysis using a blue LED combined with a Lewis acid has been developed to enable α-thiolation/annulation of carbonyls. Inexpensive, nontoxic Rose Bengal was demonstrated as the best catalyst. Hence, this transition-metal-free protocol allows mild Csp3-S couplings with both ketones and aliphatic aldehydes with a range of compatible useful functionalities.
