303172-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 303172-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,1,7 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 303172-70:
(8*3)+(7*0)+(6*3)+(5*1)+(4*7)+(3*2)+(2*7)+(1*0)=95
95 % 10 = 5
So 303172-70-5 is a valid CAS Registry Number.

New method for the synthesis of 2-substituted N,N′-diacylimidazolidines
Pokhvisneva,Luk'yanov
, p. 894 - 898 (2007/10/03)
A method for the synthesis of 2-substituted N,N′-diacylimidazolidines was developed. The method is based on the reactions of acylating reagents (carboxylic acid chlorides and anhydrides, sulfonic acid chlorides, a carbamic acid chloride, and ethyl chloroc
