1240453-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1240453-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,4,5 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1240453-50:
(9*1)+(8*2)+(7*4)+(6*0)+(5*4)+(4*5)+(3*3)+(2*5)+(1*0)=112
112 % 10 = 2
So 1240453-50-2 is a valid CAS Registry Number.

Synthesis of fused pyrimidone derivatives of 4-pyrones from the acetates of Baylis-Hillman adducts
Shahrisa,Ghasemi
experimental part, p. 30 - 36 (2010/08/06)
A series of fused pyrimidone derivatives of 4-pyrones was synthesized by conversion of the acetates of Baylis-Hillman adducts obtained from 2-formyl-4-pyrones with 2-aminopyridine and 2-aminothiazole.
