Check Digit Verification of cas no

The CAS Registry Mumber 72687-70-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,8 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72687-70:
(7*7)+(6*2)+(5*6)+(4*8)+(3*7)+(2*7)+(1*0)=158
158 % 10 = 8
So 72687-70-8 is a valid CAS Registry Number.

Copper-catalyzed cross dehydrogenative coupling reactions of tertiary amines with ketones or indoles

Yang, Fei,Li, Jian,Xie, Jin,Huang, Zhi-Zhen

supporting information; experimental part, p. 5214 - 5217 (2011/02/23)

A novel cross dehydrogenative coupling (CDC) reaction of N,N-dimethylanilines with methyl ketones by cooperative copper and aminocatalysis has been developed, which leads to the formation of β-arylamino ketones in 42-73% yields. Moreover, the copper-catal
