197067-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 197067-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,7,0,6 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 197067-77:
(8*1)+(7*9)+(6*7)+(5*0)+(4*6)+(3*7)+(2*7)+(1*7)=179
179 % 10 = 9
So 197067-77-9 is a valid CAS Registry Number.

Synthesis of a cis-conformationally restricted peptide bond isostere and its application to the inhibition of the HIV-1 protease
Abell, Andrew D.,Foulds, Glenn J.
, p. 2475 - 2482 (2007/10/03)
A synthesis of a new, tetrazole-based, cis-constrained hydroxyethylamine peptide bond isostere is reported. This has been used to produce a new class of HIV-1 protease inhibitor.
