Check Digit Verification of cas no

The CAS Registry Mumber 66449-66-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,4 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 66449-66:
(7*6)+(6*6)+(5*4)+(4*4)+(3*9)+(2*6)+(1*6)=159
159 % 10 = 9
So 66449-66-9 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.
