Check Digit Verification of cas no

The CAS Registry Mumber 1267457-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,4,5 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1267457-91:
(9*1)+(8*2)+(7*6)+(6*7)+(5*4)+(4*5)+(3*7)+(2*9)+(1*1)=189
189 % 10 = 9
So 1267457-91-9 is a valid CAS Registry Number.

Synthesis of α-ketoamides from Aryl methyl ketones and N, N -dimethylformamide via copper-catalyzed aerobic oxidative coupling

Zhou, Mingxin,Song, Qiuling

, p. 1853 - 1858 (2014/07/22)

A copper-catalyzed aerobic oxidative coupling of aryl methyl ketones with N,N-dimethylformamide was developed, which afforded α-ketoamides by a sequence of dioxygen activation, C-H bond functionalization, and amide formation with N,N-dimethylformamide as
