Check Digit Verification of cas no

The CAS Registry Mumber 893553-75-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,3,5,5 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 893553-75:
(8*8)+(7*9)+(6*3)+(5*5)+(4*5)+(3*3)+(2*7)+(1*5)=218
218 % 10 = 8
So 893553-75-8 is a valid CAS Registry Number.

New HIV-1 reverse transcriptase inhibitors based on a tricyclic benzothiophene scaffold: Synthesis, resolution, and inhibitory activity

Krajewski, Krzysztof,Zhang, Yijun,Parrish, Damon,Deschamps, Jeffrey,Roller, Peter P.,Pathak, Vinay K.

, p. 3034 - 3038 (2008/12/21)

We synthesized, separated into enantiomers, and tested for the HIV-1 reverse transcriptase inhibitory activity a group of analogs of dimethyl-1-(1-piperidynyl)cyclobuta[b][1]benzothiophene-2,2a(7bH)-dicarboxylate (NSC-380292). Absolute configurations of the enantiomers were determined based on absolute X-ray structures and analysis of CD spectra. Within pairs of enantiomers the (R,R)-enantiomer was always much more potent HIV-1 reverse transcriptase inhibitor.
