Check Digit Verification of cas no

The CAS Registry Mumber 357163-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,7,1,6 and 3 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 357163-95:
(8*3)+(7*5)+(6*7)+(5*1)+(4*6)+(3*3)+(2*9)+(1*5)=162
162 % 10 = 2
So 357163-95-2 is a valid CAS Registry Number.

A stereocontrolled 1,2-addition reaction of tetrazoles with alkyl propiolates for the synthesis of highly functionalized enamines

Luo, Kai,Meng, Lingguo,Zhang, Yicheng,Zhang, Xiuli,Wang, Lei

, p. 765 - 780 (2013/04/10)

A stereocontrolled 1,2-addition reaction of 1-aryl-1H-tetrazoles with alkyl propiolates for the synthesis of highly functionalized enamines was developed. In the presence of silver oxide (Ag2O), the 1,2-addition reaction generated (Z)-N-cyano enamines in good yields with exclusive formation of the Z-isomers. Meanwhile, the 1,2-addition reaction generated (E)-N-cyano enamines in the presence of Ag2O and potassium carbonate (K2CO 3) with high stereoselectivity and yields. Copyright
