Check Digit Verification of cas no

The CAS Registry Mumber 74007-20-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,0 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 74007-20:
(7*7)+(6*4)+(5*0)+(4*0)+(3*7)+(2*2)+(1*0)=98
98 % 10 = 8
So 74007-20-8 is a valid CAS Registry Number.

Direct C(1) Hydroxylation of Vitamin D3 and Related Compounds

Paaren, Herbert E.,DeLuca, Hector F.,Schnoes, Heinrich K.

, p. 3253 - 3258 (2007/10/02)

A direct synthesis of C(1) hydroxylated vitamin D analogues from the corresponding vitamin D precursors has been developed.Allylic oxidation of 3,5-cyclovitamin D derivatives, readily obtained from the buffered solvolysis of vitamin D tosylates, with selenium dioxide yields 1α-hydroxylated 3,5-cyclovitamin D compounds which are smoothly converted to the desired 1α-hydroxyvitamin D derivatives by acid-catalyzed cycloreversion.Application of this scheme to vitamin D3 (1a), 25-hydroxyvitamin D3 (1b), and vitamin D2 (1c) affords the 1α-hydroxy products in ca.20 percent overall yield.
