Check Digit Verification of cas no

The CAS Registry Mumber 139265-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,6 and 5 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139265-26:
(8*1)+(7*3)+(6*9)+(5*2)+(4*6)+(3*5)+(2*2)+(1*6)=142
142 % 10 = 2
So 139265-26-2 is a valid CAS Registry Number.

Comparison of deacylation rates of chymotryptic catalysis within an enantiomeric pair of p-nitrophenyl esters

Tanizawa,Yamada,Itoh,Kanaoka

, p. 2748 - 2749 (2007/10/02)

p-Nitrophenyl esters carrying a chiral acyl group were synthesized. These compounds were shown to meet the requirements of chymotrypsin for both the specific binding and the acylation. Therefore, the behavior of p-nitrophenyl esters with chymotrypsin is c
