Check Digit Verification of cas no

The CAS Registry Mumber 1392763-61-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,2,7,6 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1392763-61:
(9*1)+(8*3)+(7*9)+(6*2)+(5*7)+(4*6)+(3*3)+(2*6)+(1*1)=189
189 % 10 = 9
So 1392763-61-9 is a valid CAS Registry Number.

Coupling of enamides with alkynes or arynes for synthesis of substituted pyridines and isoquinolines via amide activation

Zhao, Mi-Na,Ren, Zhi-Hui,Wang, Yao-Yu,Guan, Zheng-Hui

, p. 8105 - 8107 (2012/09/07)

A novel and general procedure for Cu-catalyzed coupling of enamides with alkynes to synthesize substituted pyridines was developed. The chemistry was allowed to extend to the synthesis of substituted isoquinolines by coupling of enamides with arynes under transition-metal-free conditions.
