536697-61-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 536697-61-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,3,6,6,9 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 536697-61:
(8*5)+(7*3)+(6*6)+(5*6)+(4*9)+(3*7)+(2*6)+(1*1)=197
197 % 10 = 7
So 536697-61-7 is a valid CAS Registry Number.

Synthesis of 2-quinazolinonyl imidazolidinones
Reddy,Reddy, P. Pratap,Vasantha
, p. 393 - 396 (2007/10/03)
2-Chloromethyl-3-methylquinazolin-4(3H)-one 1 is converted to the azide 4 which easily undergoes cyclisation to give 2-quinazolinonyl imidazolidinones 5. The azides, however, yield 2,3-dimethylquinazolin-4(3H)-one 6 and/or 2-aryl-aminomethyl-3-methylquina
