Check Digit Verification of cas no

The CAS Registry Mumber 540740-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,0,7,4 and 0 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 540740-72:
(8*5)+(7*4)+(6*0)+(5*7)+(4*4)+(3*0)+(2*7)+(1*2)=135
135 % 10 = 5
So 540740-72-5 is a valid CAS Registry Number.

To further explore the chemical space around the entrance channel of HIV-1 reverse transcriptase (RT), a series of novel indolylarylsulfones (IASs) bearing N-substituted piperidine at indole-2-carboxamide were identified as potent HIV NNRTIs by structure-

Novel indolyl aryl sulfones active against HIV-1 carrying NNRTI resistance mutations: Synthesis and SAR studies

Silvestri, Romano,De Martino, Gabriella,La Regina, Giuseppe,Artico, Marino,Massa, Silvio,Vargiu, Laura,Mura, Massimo,Loi, Anna Giulia,Marceddu, Tiziana,La Colla, Paolo

, p. 2482 - 2493 (2007/10/03)

The potent anti-HIV-1 activities of L-737,126 (2) and PAS sulfones prompted us to design and test against HIV-1 in acutely infected MT-4 cells a number of novel 1- and 3-benzenesulfonylindoles. Indoles belonging to the 1-benzenesulfonyl series were found
