Check Digit Verification of cas no

The CAS Registry Mumber 1638139-86-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,1,3 and 9 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1638139-86:
(9*1)+(8*6)+(7*3)+(6*8)+(5*1)+(4*3)+(3*9)+(2*8)+(1*6)=192
192 % 10 = 2
So 1638139-86-2 is a valid CAS Registry Number.

Palladium-catalyzed/norbornene-mediated C-H activation/ N-tosylhydrazone insertion reaction: A route to highly functionalized vinylarenes

Zhou, Ping-Xin,Zheng, Lan,Ma, Jun-Wei,Ye, Yu-Ying,Liu, Xue-Yuan,Xu, Peng-Fei,Liang, Yong-Min

, p. 6745 - 6751 (2014/06/09)

A straightforward method for the synthesis of highly functionalized vinylarenes through palladium-catalyzed, norbornene-mediated C-H activation/carbene migratory insertion is described. Extension to a one-pot procedure is also developed. Furthermore, this
