Check Digit Verification of cas no

The CAS Registry Mumber 1344113-42-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,4,1,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1344113-42:
(9*1)+(8*3)+(7*4)+(6*4)+(5*1)+(4*1)+(3*3)+(2*4)+(1*2)=113
113 % 10 = 3
So 1344113-42-3 is a valid CAS Registry Number.

General method for the synthesis of salicylic acids from phenols through palladium-catalyzed silanol-directed C-H carboxylation

Wang, Yang,Gevorgyan, Vladimir

, p. 2255 - 2259 (2015)

A silanol-directed, palladium-catalyzed C-H carboxylation reaction of phenols to give salicylic acids has been developed. This method features high efficiency and selectivity, and excellent functional-group tolerance. The generality of this method was demonstrated by the carboxylation of estrone and by the synthesis of an unsymmetrically o,o′-disubstituted phenolic compound through two sequential C-H functionalization processes.
