Check Digit Verification of cas no

The CAS Registry Mumber 1173920-39-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,2 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1173920-39:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*2)+(3*0)+(2*3)+(1*9)=152
152 % 10 = 2
So 1173920-39-2 is a valid CAS Registry Number.

A novel one-pot, three-component synthesis of 5-imino-2,3,5,8- tetrahydropyrazolo[1,2-a]pyridazin-1-one derivatives

Qian, Bo,Fan, Ming-Jin,Xie, Yong-Xin,Wu, Lu-Yong,Shi, Yun,Liang, Yong-Min

, p. 1689 - 1693 (2009)

It was found that the zwitterionic intermediate obtained from the addition of isocyanides to dimethyl acetylenedicarboxylate could react with 1,3-dipolar compounds under mild conditions to produce 5-imino-2,3,5,8-tetrahydropyrazolo[1, 2-a]pyridazin-1-one
