Check Digit Verification of cas no

The CAS Registry Mumber 1273258-31-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,3,2,5 and 8 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1273258-31:
(9*1)+(8*2)+(7*7)+(6*3)+(5*2)+(4*5)+(3*8)+(2*3)+(1*1)=153
153 % 10 = 3
So 1273258-31-3 is a valid CAS Registry Number.

Pseudo-peptides derived from isomannide: Inhibitors of serine proteases

Barros, Thalita G.,Pinheiro, Sergio,Williamson,Tanuri, Amilcar,Gomes Jr.,Pereira, Helena S.,Brindeiro,Neto, Jose B. A.,Antunes,Muri, Estela M. F.

, p. 701 - 709 (2010)

In this paper, we describe the synthesis of a novel class of pseudo-peptides derived from isomannide and several oxazolones as potential inhibitors of serine proteases as well as preliminary pharmacological assays for hepatitis C. Hepatitis C, dengue and West Nile fever are among the most important flaviviruses that share one important serine protease enzyme. Serine proteases belong to the most studied class of proteolytic enzymes and are a primary target in the drug development field. Several pseudo-peptides were obtained in good yields from the reaction of isomannide and oxazolones, and their anti-HCV potential using the HCV replicon-based assay was shown.
