Check Digit Verification of cas no

The CAS Registry Mumber 207444-85-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,4,4 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 207444-85:
(8*2)+(7*0)+(6*7)+(5*4)+(4*4)+(3*4)+(2*8)+(1*5)=127
127 % 10 = 7
So 207444-85-7 is a valid CAS Registry Number.

Syntheses of HIV-protease inhibitors having a peptide moiety which binds to GP120

Asagarasu, Akira,Uchiyama, Taketo,Achiwa, Kazuo

, p. 697 - 703 (2007/10/03)

Some HIV-protease inhibitor derivatives having an N- carbomethoxycarbonyl-prolyl-phenylalanine benzyl ester (CPF) moiety as a binding site to gp120 were designed and synthesized. Almost all the compounds bearing CPF on the phenoxyacetyl group showed protease-inhibitory activity. Compounds 25a and 25b, which have the CPF moiety at the ortho- and meta- positions of the phenoxyacetyl group, respectively, had anti-HIV activity, although the others showed only protease-inhibitory activity. These results suggest that 25b binds to gp120 and inhibits HIV protease.
