Check Digit Verification of cas no

The CAS Registry Mumber 134523-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,5,2 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 134523-85:
(8*1)+(7*3)+(6*4)+(5*5)+(4*2)+(3*3)+(2*8)+(1*5)=116
116 % 10 = 6
So 134523-85-6 is a valid CAS Registry Number.

Total synthesis of 1α,25-dihydroxyvitamin D3 analogs modified at the side chain and D-ring

López-Pérez, Borja,Maestro, Miguel A.,Mouri?o, Antonio

, p. 4563 - 4569 (2018/06/29)

Herein, we describe a synthetic strategy to access 1α,25-dihydroxyvitamin D3 (calcitriol) analogs with natural or unnatural configuration at C20 and unsaturation at the D-ring. The synthetic approach is exemplified by the synthesis of two potent analogs, namely 1α,25-dihydroxy-16-en-23-yne-vitamin D3 and 1α,25-dihydroxy-20-epi-24a-homo-26,27-dimethyl-vitamin D3. A key feature of the synthetic strategy is the generation of an unnatural configuration at C20 by a catalytic asymmetric reduction of an α,β,γ,δ-unsaturated ester with the CuH species in a micellar system.
