22293-60-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22293-60-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,2,9 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22293-60:
(7*2)+(6*2)+(5*2)+(4*9)+(3*3)+(2*6)+(1*0)=93
93 % 10 = 3
So 22293-60-3 is a valid CAS Registry Number.

NUCLEAR TRANSFORMATIONS BY HYDROGENOLYSIS: SYNTHESIS OF PYRIMIDINONES FROM ISOXAZOLES DERIVATIVES
Caronna, Sergio,Migliara, Onofrio,Petruso, Salvatore
, p. 1377 - 1380 (2007/10/02)
Pyrimidinones derivatives are obtained by catalytic hydrogenation of the products resulting from the condensation of 3,5-dimethylisoxazole-4-carboxylic acid chloride with urea (or benzamidine).
