Check Digit Verification of cas no

The CAS Registry Mumber 642976-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,9,7 and 6 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 642976-92:
(8*6)+(7*4)+(6*2)+(5*9)+(4*7)+(3*6)+(2*9)+(1*2)=199
199 % 10 = 9
So 642976-92-9 is a valid CAS Registry Number.

Synthesis of N-benzothiazol-2-yl-amides by Pd-catalyzed C(sp2)-H functionalization

Wang, Jun-Ke,Zong, Ying-Xiao,Wang, Xi-Cun,Hu, Yu-Lai,Yue, Guo-Ren

, p. 1376 - 1380 (2015/10/28)

A catalytic synthesis of N-benzothiazol-2-yl-amides from 1-acyl-3-(phenyl)thioureas was achieved in the presence of a palladium catalyst through the C(sp2)-H functionalization/C-S bond formation. This synthetic methodology can produce various N
