Check Digit Verification of cas no

The CAS Registry Mumber 1385660-20-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,5,6,6 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1385660-20:
(9*1)+(8*3)+(7*8)+(6*5)+(5*6)+(4*6)+(3*0)+(2*2)+(1*0)=177
177 % 10 = 7
So 1385660-20-7 is a valid CAS Registry Number.

Palladium-catalyzed cyclization of o-alkynyltrifluoroacetanilides followed by isocyanide insertion: Synthesis of 2-substituted 1H-indole-3-carboxamides

Hu, Ziwei,Liang, Dongdong,Zhao, Jiaji,Huang, Jinbo,Zhu, Qiang

supporting information; experimental part, p. 7371 - 7373 (2012/09/22)

A base-controlled synthesis of 2-substituted secondary and tertiary 1H-indole-3-carboxamides through PdCl2-catalyzed cyclization of o-alkynyltrifluoroacetanilides followed by isocyanide insertion has been developed. The reaction proceeds smoothly at ambient temperature using O 2 in air as the sole oxidant of the palladium catalyst.
