Check Digit Verification of cas no

The CAS Registry Mumber 52186-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,1,8 and 6 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 52186-49:
(7*5)+(6*2)+(5*1)+(4*8)+(3*6)+(2*4)+(1*9)=119
119 % 10 = 9
So 52186-49-9 is a valid CAS Registry Number.

Photoredox-Catalyzed Decarboxylative Alkylation of Silyl Enol Ethers to Synthesize Functionalized Aryl Alkyl Ketones

Kong, Weiguang,Yu, Changjiang,An, Hejun,Song, Qiuling

, p. 349 - 352 (2018)

Photoredox-catalyzed decarboxylative alkylation of silyl enol ethers has been developed. Diverse functionalized aryl alkyl ketones were afforded in modest to good yields using N-(acyloxy)phthalimide as an easy access alkyl radical source under mild and operationally simple conditions. The excellent performance of drug molecules such as fenbufen and indomethacin and naturally occurring carboxylic acids such as stearic acid and dehydrocholic acid further demonstrated the practicability of the reaction.
