955031-19-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 955031-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,5,0,3 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 955031-19:
(8*9)+(7*5)+(6*5)+(5*0)+(4*3)+(3*1)+(2*1)+(1*9)=163
163 % 10 = 3
So 955031-19-3 is a valid CAS Registry Number.

Synthesis of substituted 2-amino-5,6-dihydropyrimidin-4-ones using an aza-Wittig reaction
Kochubey,Blochin,Rodin,Perevalov
, p. 897 - 900 (2008/02/10)
An aza-Wittig reaction has been used for the first time in the synthesis of substituted 2-amino-5,6-dihydropyrimidin-4-ones via condensation of triphenyliminophosphoranes with aromatic heterocumulenes (arylisocyanates and thiocyanates).
