Check Digit Verification of cas no

The CAS Registry Mumber 315229-51-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,5,2,2 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 315229-51:
(8*3)+(7*1)+(6*5)+(5*2)+(4*2)+(3*9)+(2*5)+(1*1)=117
117 % 10 = 7
So 315229-51-7 is a valid CAS Registry Number.

Synthesis of chiral piperazinones as versatile scaffolds for peptidomimetics

Rübsam, Frank,Mazitschek, Ralph,Giannis, Athanassios

, p. 8481 - 8487 (2000)

Chiral piperazinones were synthesized as conformationally restricted peptidomimetics starting from inexpensive and readily available D-glucosamine hydrochloride and amino acid methyl esters. Different synthetic strategies are devised to allow attachment of side chains imitating the parent peptide as shown for the RGD motif. (C) 2000 Elsevier Science Ltd.
