23131-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23131-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,3 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23131-01:
(7*2)+(6*3)+(5*1)+(4*3)+(3*1)+(2*0)+(1*1)=53
53 % 10 = 3
So 23131-01-3 is a valid CAS Registry Number.

One-Step Synthesis of 3-Amino-2,4-imidazolinediones (3-Aminohydantoins) From α-Amino Acids
Lalezari, Iraj
, p. 741 - 743 (2007/10/02)
α-Amino acids melted with ethyl or t-butyl carbazate or, preferably, refluxed with t-butyl carbazate in quinoline gave high yields of 3-amino-2,4-imidazolidinediones (3-aminohydantoins).
