Check Digit Verification of cas no

The CAS Registry Mumber 81928-67-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,2 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 81928-67:
(7*8)+(6*1)+(5*9)+(4*2)+(3*8)+(2*6)+(1*7)=158
158 % 10 = 8
So 81928-67-8 is a valid CAS Registry Number.

CHROMOGENIC SUBSTRATES FOR PAPAIN WITH A C-TERMINAL S-BENZYLCYSTEINE RESIDUE

Kasafirek, Evzen,Fukal, Ladislav,Kas, Jan

, p. 3197 - 3205 (2007/10/02)

Two types of chromogenic substrates for papain were prepared, namely p-nitroanilides of N-acetyltripeptides of general formula Ac-Leu-Leu-A-NAn, where A = Gly, Ala, Leu, and p-nitroanilides of 3-carboxypropionyldi- and tripeptides of general formula Suc-B-Cys(Bzl)-NAn, where B = Gly, Gly-Gly, Ala, Ala-Ala, Leu, Leu-Leu, Gly-Leu, Leu-Ala and Ala-Met.The values of Km, kcat and C (kcat/Km) for these substrates were determined.Suc-Leu-Leu-Cys(Bzl)-NAn is the best substrate for papain its C being 60 000 mol-1 l s-1.
