Check Digit Verification of cas no

The CAS Registry Mumber 1201947-31-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,9,4 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1201947-31:
(9*1)+(8*2)+(7*0)+(6*1)+(5*9)+(4*4)+(3*7)+(2*3)+(1*1)=120
120 % 10 = 0
So 1201947-31-0 is a valid CAS Registry Number.

Triphenylphosphine-mediated eco-friendly synthesis of (Z)-diisopropyl-2- (Cyano(Aryl)Methylene)hydrazine-1,1-dicarboxylates using potassium hexacyanoferrate(II) as a cyanide source

Hu, Xiaochun,Zhao, Zhouxing,Li, Zheng

experimental part, p. 1003 - 1008 (2012/08/07)

A triphenylphosphine-mediated synthetic method for (Z)-diisopropyl-2-(cyano (aryl)methylene)hydrazine-1,1-dicarboxylates via one-pot three-component reactions using potassium hexacyanoferrate(II) as a cyanide source was described. This protocol has advantages of no use of strong toxic cyanating agents, high yield, and simple work-up procedure.
