Check Digit Verification of cas no

The CAS Registry Mumber 121613-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,6,1 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 121613-69:
(8*1)+(7*2)+(6*1)+(5*6)+(4*1)+(3*3)+(2*6)+(1*9)=92
92 % 10 = 2
So 121613-69-2 is a valid CAS Registry Number.

Sugar-amino acid cyclic conjugates as novel conformationally constrained hydroxyethylamine transition-state isosteres

Roy, Arup,Sanjayan, Gangadhar J.

, p. 3361 - 3363 (2012/07/28)

Hydroxyethylamine (HEA) isosteres have previously been shown to display a multitude of biomedical applications. In fact, the first protease inhibitor, saquinavir is an HEA based peptidomimetic. Herein we describe an easy-to-operate synthetic route to a series of carbohydrate-based conformationally constrained hydroxyethylamine (HEA) isosteres featuring amino acid side chains, starting from d-glucose. This class of novel sugar-amino acid-tethered conformationally restricted HEA systems may have bearing in practical application, particularly in the development of conformationally restricted protease inhibitors.
