Check Digit Verification of cas no

The CAS Registry Mumber 147200-39-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,2,0 and 0 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 147200-39:
(8*1)+(7*4)+(6*7)+(5*2)+(4*0)+(3*0)+(2*3)+(1*9)=103
103 % 10 = 3
So 147200-39-3 is a valid CAS Registry Number.

A new synthesis of 24-fluoro-1α,25-dihydroxyvitamin D2 and its 24-epimer, and determination of the C-24 configuration

Hayashi,Ojima,Konno,Manaka,Yamaguchi,Yamada,Takayama

, p. 2932 - 2936 (1992)

A new synthesis of 24-fluoro-1α,25-dihydroxyvitamin D2 (4a) and its 24-epimer (4b) is described. Starting with 1α,3β-bis[(tert-butyldimethylsilyl)oxy]-24-norchol-5,7-dien-23-al (5), a mixture of 4a and 4b was obtained in 3% overall yield in 6 s
