Check Digit Verification of cas no

The CAS Registry Mumber 1372616-57-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,6,1 and 6 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1372616-57:
(9*1)+(8*3)+(7*7)+(6*2)+(5*6)+(4*1)+(3*6)+(2*5)+(1*7)=163
163 % 10 = 3
So 1372616-57-3 is a valid CAS Registry Number.

Regioselective C-S bond formation accomplished by copper-catalyzed regioselective C-F substitution of perfluoroarenes with aryl thioacetates or benzyl thioacetate

Zhou, Qizhong,Zhang, Bin,Du, Tieqi,Gu, Haining,Jiang, Huajiang,Chen, Rener

experimental part, p. 4233 - 4241 (2012/07/14)

Practical and straightforward method for regioselective C-S bond formation accomplished by copper-catalyzed regioselective C-F substitution of electron-deficient perfluoroarenes with aryl thioacetates or benzyl thioacetate has been developed. Because of its high reaction efficiency, good chemoselectivity and regioselectivity, and excellent functional-group compatibility, this protocol provides a useful and operationally simple access to polyfluoroaryl thioethers used for drugs and material chemistry.
