Check Digit Verification of cas no

The CAS Registry Mumber 170081-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,0,8 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 170081-43:
(8*1)+(7*7)+(6*0)+(5*0)+(4*8)+(3*1)+(2*4)+(1*3)=103
103 % 10 = 3
So 170081-43-3 is a valid CAS Registry Number.

A stereospecific synthesis of 24(S)-hydroxyvitamin D2, a prodrug for 1α,24(S)-dihydroxyvitamin D2

Coutts, Lisa D.,Geiss, William B.,Gregg, Brian T.,Helle, Mark A.,King, Chi-Hsin R.,Itov, Zinovy,Mateo, Mary E.,Meckler, Harold,Zettler, Mark W.,Knutson, Joyce C.

, p. 246 - 255 (2013/09/06)

This contribution describes the first stereospecific synthesis of 24(S)-hydroxyvitamin D2 (1), a metabolite of vitamin D2. This metabolite acts as a prodrug for 1α,24(S)-dihydroxyvitamin D2 (2), which is under development for treatment of various diseases characterized by cellular hyperproliferation. The key step of the synthesis involves the Wittig-Horner olefination of (S)-2,3-dimethyl-2-triethysilyloxybutyraldehyde (17) and a vitamin D2 phosphine oxide derivative (22). The synthesis of the requisite aldehyde started with the commercially available L-(+)-valine and was completed in seven steps. The vitamin D2 phosphine oxide derivative was synthesized in seven steps starting from vitamin D2.
