Check Digit Verification of cas no

The CAS Registry Mumber 1028257-74-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,8,2,5 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1028257-74:
(9*1)+(8*0)+(7*2)+(6*8)+(5*2)+(4*5)+(3*7)+(2*7)+(1*4)=140
140 % 10 = 0
So 1028257-74-0 is a valid CAS Registry Number.

Synthesis and anti-HIV-1 activity evaluation of 5-alkyl-2-alkylthio-6- (arylcarbonyl or α-cyanoarylmethyl)-3,4-dihydropyrimidin-4(3H)-ones as novel non-nucleoside HIV-1 reverse transcriptase inhibitors

, p. 1778 - 1786 (2008/02/01)

A series of novel S-DABO analogues (S-DABOs, 1) were synthesized and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). Key structural modifications included replacement of the 6-arylmethyl group by a 6-arylcarbonyl or 6-(α-cyanoarylmethyl) group. Most of the compounds showed only micromolar potency against HIV-1 in MT-4 cells in vitro, though two of them (3e and 3g) were unusually potent (IC50 = 0.09 and 0.002 μM, respectively) and selective (SI = 1500 and 4600, respectively). Structure-activity relationships among the newly synthesized S-DABOs are discussed.
