89018-41-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89018-41-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,0,1 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89018-41:
(7*8)+(6*9)+(5*0)+(4*1)+(3*8)+(2*4)+(1*1)=147
147 % 10 = 7
So 89018-41-7 is a valid CAS Registry Number.

, p. 2540 - 2551 (2007/10/02)
The synthesis of imidazopyrimidines from 2-substituted pyrimidin-4(3H)-ones is described. 2--6-methylpyrimidin-4(3H)-ones, prepared by the reaction of β-aminocrotonamide with N-acylated amino acid esters, were treated with POCl3
