Check Digit Verification of cas no

The CAS Registry Mumber 1616604-32-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,6,6,0 and 4 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1616604-32:
(9*1)+(8*6)+(7*1)+(6*6)+(5*6)+(4*0)+(3*4)+(2*3)+(1*2)=150
150 % 10 = 0
So 1616604-32-0 is a valid CAS Registry Number.

New synthesis of ethyl 6-amino-4-aryl-5-cyano-1,4-dihydropyrano[2,3-c] pyrazole-3-carboxylates

Gein,Zamaraeva,Kozulina

, p. 691 - 693 (2014)

Ethyl 6-amino-4-aryl-5-cyano-1,4-dihydropyrano[2,3-c]pyrazol-3-carboxylates were synthesized by a reaction of diethyloxalacetate sodium salt with aromatic aldehyde, hydrazine hydrate, and malononitrile in the presence of acetic acid.
