Check Digit Verification of cas no

The CAS Registry Mumber 191471-30-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,7 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 191471-30:
(8*1)+(7*9)+(6*1)+(5*4)+(4*7)+(3*1)+(2*3)+(1*0)=134
134 % 10 = 4
So 191471-30-4 is a valid CAS Registry Number.

Palladium-catalyzed carbonylation of benzylic ammonium salts to amides and esters: Via C-N bond activation

Yu, Weijie,Yang, Shuwu,Xiong, Fei,Fan, Tianxiang,Feng, Yan,Huang, Yuanyuan,Fu, Junkai,Wang, Tao

supporting information, p. 3099 - 3103 (2018/05/22)

An efficient palladium-catalyzed carbonylation reaction of readily available quaternary ammonium salts with CO is reported for the first time to afford arylacetamides and arylacetic acid esters via benzylic C-N bond cleavage. This protocol features mild reaction conditions under atmospheric pressure of CO, a redox-neutral process without an additional oxidant, and a broad substrate scope for various kinds of amines, alcohols and phenols.
