Check Digit Verification of cas no

The CAS Registry Mumber 1268830-97-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,8,8,3 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1268830-97:
(9*1)+(8*2)+(7*6)+(6*8)+(5*8)+(4*3)+(3*0)+(2*9)+(1*7)=192
192 % 10 = 2
So 1268830-97-2 is a valid CAS Registry Number.

Copper-catalyzed oxidative cross-coupling of N,N-Dimethylanilines with heteroarenes under molecular oxygen

Huang, Lehao,Niu, Tianmin,Wu, Jun,Zhang, Yuhong

, p. 1759 - 1766 (2011/05/28)

Nitrogen-containing heterocyclic compounds are important motifs of pharmaceuticals and functional materials, and there has been a growing interest in new synthetic methods for their preparation. In this paper, we report a direct cross-coupling reaction of heteroarenes with N,N-dimethylanilines in the presence of copper catalyst. Oxygen and/or air are successfully used as the oxidant, which is of great importance to the industrialized economies. The reaction is compatible with a wide range of heterocycles, including indolizines, imidazoles, indoles, and aniline, to enable the formation of various alkylated heteroarenes under very mild reaction conditions.
