Check Digit Verification of cas no

The CAS Registry Mumber 138834-76-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,3 and 4 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 138834-76:
(8*1)+(7*3)+(6*8)+(5*8)+(4*3)+(3*4)+(2*7)+(1*6)=161
161 % 10 = 1
So 138834-76-1 is a valid CAS Registry Number.

Novel inhibitors of prolyl 4-hydroxylase

Dowell,Hadley

, p. 800 - 804 (2007/10/02)

A series of 5-acyl sulfonamides derived from pyridine-2,5-dicarboxylic acid (15) has been prepared and several members of this series have been shown to be more potent, in vitro, as inhibitors of prolyl 4-hydroxylase than 15. Several chain-extended pyridinedicarboxylic acids have also been prepared and shown to be potent inhibitors of prolyl 4-hydroxylase. The structure- activity in both these series is discussed. The results indicate that the 5- carboxylic acid binding site, in the enzyme, can accept a carboxylic acid or an acyl sulfonamide equally well. This indicates a much greater degree of freedom in this distal carboxylic acid binding site than is predicted by the current theorical model of the active site.
