Check Digit Verification of cas no

The CAS Registry Mumber 1031238-96-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,1,2,3 and 8 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1031238-96:
(9*1)+(8*0)+(7*3)+(6*1)+(5*2)+(4*3)+(3*8)+(2*9)+(1*6)=106
106 % 10 = 6
So 1031238-96-6 is a valid CAS Registry Number.

Synthesis of novel (3a,S)-1-aryl/aryloxy/alkoxy-3a,4-dihydro-3H-1λ5- [1,3,2]oxazaphospholo [3,4-a] indole-1-ones, thiones, and selenones

Synthesis of novel (3a,S)-1-aryl/aryloxy/alkoxy-3a,4-dihydro-3H-1λ5- [1,3,2]oxazaphospholo [3,4-a] indole-1-ones, thiones, and selenones was achieved in two steps with high yields from 2,3-dihydro-1H-indol-2(S)yl methanol (1) and dichlorophenyl phosphine/ethyl dichlorophosphite (2a and b) in the presence of triethylamine in dry THF followed by treatment with hydrogen peroxide, sulfur, and selenium. The compounds 4g-k have been synthesized by the direct cyclocondensation of 1 with different substituted phenyl phosphorodichloridates (2c-e, g) and bis(2-chloroethyl) phosphoramidic dichloride (2f).
