Check Digit Verification of cas no

The CAS Registry Mumber 1643864-41-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,8,6 and 4 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1643864-41:
(9*1)+(8*6)+(7*4)+(6*3)+(5*8)+(4*6)+(3*4)+(2*4)+(1*1)=188
188 % 10 = 8
So 1643864-41-8 is a valid CAS Registry Number.

Palladium-catalyzed oxidative carbonylation of aromatic C-H bonds of N -alkylanilines with CO and alcohols for the synthesis of o -aminobenzoates

Chen, Ming,Ren, Zhi-Hui,Wang, Yao-Yu,Guan, Zheng-Hui

, p. 1258 - 1263 (2015/01/30)

A Pd(II)-catalyzed C-H monocarbonylation of N-alkylanilines for the synthesis of o-aminobenzoates has been developed. Various aliphatic alcohols and phenol were tolerated in the reaction to afford the corresponding o-aminobenzoates in good yields under mild balloon pressure of CO.
