Check Digit Verification of cas no

The CAS Registry Mumber 56777-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,6,7,7 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 56777-82:
(7*5)+(6*6)+(5*7)+(4*7)+(3*7)+(2*8)+(1*2)=173
173 % 10 = 3
So 56777-82-3 is a valid CAS Registry Number.

Phosphonodipeptides: synthesis and separation of diastereoisomers

Kafarski, Pawel,Lejczak, Barbara,Mastalerz, Przemslaw,Szewczyk, Jerzy,Wasielewski, Czeslaw

, p. 3081 - 3084 (2007/10/02)

Diastereoisomeric mixtures of phosphonodipeptides, prepared from racemic dialkyl 1-aminoalkanephosphonates, were separated by ion-exchange column chromatography.Phosphonodipeptides were found to be much more readily available from dialkyl 1-aminoalkanephosphonates than from the corresponding free acids and the mixed carboxylic-carbonic anhydride method was found to be the most effective one.
