Check Digit Verification of cas no

The CAS Registry Mumber 220131-62-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,1,3 and 1 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 220131-62:
(8*2)+(7*2)+(6*0)+(5*1)+(4*3)+(3*1)+(2*6)+(1*2)=64
64 % 10 = 4
So 220131-62-4 is a valid CAS Registry Number.

Possible rearrangements during the syntheses of Di- and trisubstituted pyrazoles

Reidlinger, Claudia,Dworczak, Renate,Junek, Hans,Graubaum, Heinz

, p. 1313 - 1318 (2007/10/03)

The reaction of ethoxymethylene malononitrile and ethoxymethylene cyanoacetic acid ethylester with substituted hydrazines to substituted 5-aminopyrazoles is described. The influence of different substituents on possible migrations during the ring closure was studied.
