Check Digit Verification of cas no

The CAS Registry Mumber 77-84-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 7 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 77-84:
(4*7)+(3*7)+(2*8)+(1*4)=69
69 % 10 = 9
So 77-84-9 is a valid CAS Registry Number.

Synthesis and evaluation of α,α -disubstituted-3-mercaptopropanoic acids as inhibitors for carboxypeptidase A and implications with respect to enzyme inhibitor design

Lee, Hyun Soo,Kim, Dong H.

, p. 4685 - 4691 (2007/10/03)

2-Ethyl-2-methyl-3-mercaptopropanoic acid (6) and 2-benzyl-2-methyl-3-mercaptopropanoic acid (7) were synthesized and evaluated as inhibitors for carboxypeptidase A (CPA), a prototypical zinc protease with the expectation that the binding affinities of these inhibitors would be augmented over those of 2-ethyl-3-methylsuccinic acid (2) and 2-benzyl-3-methylsuccinic acid (3), respectively, in light of the fact that the sulfhydryl group is a better zinc coordinating moiety than the carboxylate group. Contrary to the expectation, however, the inhibitory potency of 6 was not improved and that of 7 was rather attenuated by the replacement. A probable explanation for the unexpected results is offered.
