Check Digit Verification of cas no

The CAS Registry Mumber 288590-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,5,9 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 288590-33:
(8*2)+(7*8)+(6*8)+(5*5)+(4*9)+(3*0)+(2*3)+(1*3)=190
190 % 10 = 0
So 288590-33-0 is a valid CAS Registry Number.

Inhibition of HIV-1 integrase-catalysed reaction by new DNA minor groove ligands: The oligo-1,3-thiazolecarboxamide derivatives

Human immunodeficiency virus type 1 (HIV-1) integrase (IN) is an essential enzyme in the life cycle of the retrovirus, responsible for catalysing the insertion of the viral genome into the host cell chromosome. For this reason it provides an attractive target for antiviral drug design. We synthesized a series of novel thiazole (Tz)-containing oligopeptides (TCOs; oligo-1,3-thiazolecarboxamides), specifically interacting within the minor groove of DNA. The oligocarboxamide derivatives contained 1-4 Tz rings and different N- and C-terminal groups. The effect of these oligocarboxamides on the HIV-1 IN-catalysed reaction was investigated. Some of the compounds were able to inhibit the reaction. The inhibitory effect of the TCOs increased with the number of Tz units. The structure of various additional positively and/or negatively charged groups attached to the N- and C-termini of TCOs had a pronounced effect on their interaction with the DNA substrate complexed to IN. Modified TCOs having a better affinity for this complex should provide a rationale for the design of drugs targeting the integration step. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
