Check Digit Verification of cas no
The CAS Registry Mumber 130313-06-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,3,1 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 130313-06:
(8*1)+(7*3)+(6*0)+(5*3)+(4*1)+(3*3)+(2*0)+(1*6)=63
63 % 10 = 3
So 130313-06-3 is a valid CAS Registry Number.

SYNTHESIS OF AN OPTICALLY ACTIVE 13β-METHYL 14β-HYDROXY STEROID VIA BASE-CATALYZED REACTIONS
Ruel, Rejean,Deslongchamps, Pierre
, p. 3961 - 3964 (2007/10/02)
The synthesis of optically active 14β-hydroxy steroid 9 is reported.This steroid is obtained in only two steps from chiral precursors 6 and 7 via anionic cycloaddition followed by base-catalyzed aldol reaction of tricetone 8.
