1373955-96-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1373955-96-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,3,9,5 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1373955-96:
(9*1)+(8*3)+(7*7)+(6*3)+(5*9)+(4*5)+(3*5)+(2*9)+(1*6)=204
204 % 10 = 4
So 1373955-96-4 is a valid CAS Registry Number.

One-pot three-component synthesis of 4-aryl-3,4-dihydro-pyrimidin- 2(1H)-thiones catalyzed by Ni loaded SiO2
Maddila, Suresh,Jonnalagadda, Sreekanth B.
, p. 121 - 126 (2012)
A simple and efficient method has been developed for the synthesis of 4-aryl-3,4- dihydropyrimidin-2(1H)-thiones from methyl 3-oxopentanoate, aldehydes and thiourea in the presence of a catalytic amount of Ni loaded SiO2 at room temperature.
