23073-70-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 23073-70-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,0,7 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 23073-70:
(7*2)+(6*3)+(5*0)+(4*7)+(3*3)+(2*7)+(1*0)=83
83 % 10 = 3
So 23073-70-3 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).
