Check Digit Verification of cas no

The CAS Registry Mumber 244190-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,1,9 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 244190-87:
(8*2)+(7*4)+(6*4)+(5*1)+(4*9)+(3*0)+(2*8)+(1*7)=132
132 % 10 = 2
So 244190-87-2 is a valid CAS Registry Number.

A number of 1-aroyl/aryloxyaceto-4-aryl-5-cyano-3-methyl 1,4,5,6,7- pentahydropyrazolo[4,5-e] pyridin-6-ones 3 and 1-aroyl/aryloxyaceto-4-aryl- 3-methyl-1,4-dihydropyrazolo[4,5-e]pyrido[1,2-α]pyrimidines 4 have been prepared by Michael addition between α,β-unsaturated ketones 2 and ethyl cyanoacetate/2-arninopyridine in the presence of ammonium acetate. These compounds have been evaluated for their fungistatic activity against P. oryzae, R. solani, P cubensis and P infestans.
