87275-51-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87275-51-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,7 and 5 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87275-51:
(7*8)+(6*7)+(5*2)+(4*7)+(3*5)+(2*5)+(1*1)=162
162 % 10 = 2
So 87275-51-2 is a valid CAS Registry Number.

Harode, Raju,Sharma
, p. 627 - 628 (2007/10/03)
While reaction of chalcone dibromides (1) with urea in acetic acid is known to give 5-aryl-4-α-bromobenzylimidazolin-2-ones (2), that of 4-methoxychalcone dibromides afforded 4-aryl-5-arylmethineimidazolin-2-ones (4) and 4,6-diaryl-5-bromo-5,6-dihydropyrimidin-2(1H)-ones (5).
