Check Digit Verification of cas no

The CAS Registry Mumber 1290637-13-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,0,6,3 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1290637-13:
(9*1)+(8*2)+(7*9)+(6*0)+(5*6)+(4*3)+(3*7)+(2*1)+(1*3)=156
156 % 10 = 6
So 1290637-13-6 is a valid CAS Registry Number.

Synthesis and studies of new 6-[halo(diphenyl)methyl]- and 6-(thiophen-2-ylmethyl)pyrimidin-4(3H)-ones as possible HIV-1 reverse transcriptase inhibitors

Valuev-Elliston,Ivanov,Orlinson,Gerasimov,Brunilina,Zakharova,Kochetkov,Novakov,Navrotskii

, p. 797 - 801 (2013)

Six new 6-[halo(diphenyl)methyl]- and 6-(thiophen-2-ylmethyl)pyrimidin- 4(3H)-one derivatives were synthesized and studied for biological activity. The studies showed that the 6-(thiophen-2-ylmethyl)pyrimidin-4(3H)-one derivatives inhibited activity of the HIV-1 recombinant reverse transcriptase in the micromolar range of concentrations. The 6-[halo-(diphenyl)methyl]pyrimidin-4(3H) -one derivative showed no activity in the concentrations up to 200 μmol mL-1.
