173091-94-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173091-94-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,0,9 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 173091-94:
(8*1)+(7*7)+(6*3)+(5*0)+(4*9)+(3*1)+(2*9)+(1*4)=136
136 % 10 = 6
So 173091-94-6 is a valid CAS Registry Number.

Pyrrolinone-based peptidomimetics, the first mimics of β-strands, are potent inhibitors of HIV-1 protease. Importantly, the bis(pyrrolinones) described herein proved to be more active in cellular antiviral assays compared with an analogous peptide-derived
