Check Digit Verification of cas no

The CAS Registry Mumber 401942-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,1,9,4 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 401942-25:
(8*4)+(7*0)+(6*1)+(5*9)+(4*4)+(3*2)+(2*2)+(1*5)=114
114 % 10 = 4
So 401942-25-4 is a valid CAS Registry Number.

SYNTHESIS AND PROPERTIES OF PEPTIDE FRAGMENTS OF THE S-REGION OF THE SURFACE PROTEIN OF THE HEPTATITIS B VIRUS

Kuranova, I. L.,Churkina, S. I.,Os'mak, A. V.,Filonova, E. B.,Lyudmirova, V. L.,Noskova, O. V.

, p. 355 - 361 (2007/10/02)

A peptide fragment with the 140-146 sequence of the main component of the surface protein of the hepatitis B virus (HBsAG) and a number of its structural analogues have been synthesized by the classical method in solution.Conjugates of the peptides synthesized with bovine serum albumin and with a synthetic polypeptide analogue of polytuftsin have been obtained.The ability of the preparations to bind antibodies from the blood sera of hepatitis B patients has been studied.The possibility has been shown of their use for revealing antibodies to the heptatitis B virus in solid-phase enzyme-mediated immunoassay.
