Check Digit Verification of cas no

The CAS Registry Mumber 1240155-59-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,1,5 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1240155-59:
(9*1)+(8*2)+(7*4)+(6*0)+(5*1)+(4*5)+(3*5)+(2*5)+(1*9)=112
112 % 10 = 2
So 1240155-59-2 is a valid CAS Registry Number.

Synthesis and reactivity of methyl 3-acyl-6-amino-4-aryl-5-cyano-4h-pyran- 2-carboxylates

Sheverdov,Andreev, A. Yu.,Ershov,Nasakin,Tafeenko,Gein

, p. 997 - 1005 (2013/03/13)

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
