128923-36-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128923-36-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,2 and 3 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 128923-36:
(8*1)+(7*2)+(6*8)+(5*9)+(4*2)+(3*3)+(2*3)+(1*6)=144
144 % 10 = 4
So 128923-36-4 is a valid CAS Registry Number.

Potent Inhibition of Pepsin and Penicillopepsin by Phosphorus-Containing Peptide Analogues
Bartlett, Paul A.,Hanson, John E.,Giannousis, Peter P.
, p. 6268 - 6274 (2007/10/02)
Phosphinic and phosphonic acid peptide derivatives have been evaluated as inhibitors of the aspartic proteases pepsin and penicillopepsin.The most potent of those studied is isovaleryl-Val-Val-LeuP-(O)Phe-Ala-Ala-OMe (4) (LeuP repres
