Check Digit Verification of cas no

The CAS Registry Mumber 503167-42-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,3,1,6 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 503167-42:
(8*5)+(7*0)+(6*3)+(5*1)+(4*6)+(3*7)+(2*4)+(1*2)=118
118 % 10 = 8
So 503167-42-8 is a valid CAS Registry Number.

2-Azidoethoxy derivatives of 2-aminocyclohexanecarboxylic acids (ACHC): Interesting building blocks for the synthesis of cyclic β-peptide conjugates

Reina, Jose J.,Bernardi, Anna

, p. 5770 - 5775 (2011)

Oligomers of cyclic-β-aminoacids possess a high resistance to peptidase-catalyzed hydrolysis and display a high intrinsic tendency to adopt regular secondary structures. These characteristics are attractive to develop new biologically active substances. H
