Check Digit Verification of cas no

The CAS Registry Mumber 1240193-14-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,9 and 3 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1240193-14:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*9)+(3*3)+(2*1)+(1*4)=109
109 % 10 = 9
So 1240193-14-9 is a valid CAS Registry Number.

, p. 997 - 1005 (2012)

By treating arylidenemalononitriles with methyl 2,4-dioxobutanoates, derivatives of 4H-pyrans - methyl 3-acyl-6-amino-4-aryl-5-cyano-4H-pyran-2- carboxylates - are obtained, which are novel, promising structural components for the synthesis of carbo- and
