203303-83-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 203303-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 203303-83:
(8*2)+(7*0)+(6*3)+(5*3)+(4*0)+(3*3)+(2*8)+(1*3)=77
77 % 10 = 7
So 203303-83-7 is a valid CAS Registry Number.

Inhibition of aminopeptidases by peptides containing ketomethylene and hydroxyethylene amide bond replacements
Harbeson,Rich
, p. 1378 - 1392 (2007/10/02)
Inhibitors of aminopeptidase enzymes have been prepared by the synthesis of peptide substrate analogues in which the scissile amide bond has been replaced with the hydrolytically stable ketomethylene (-COCH2-) and hydroxyethylene [-CH(OH)CHsub
