145345-95-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145345-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,3,4 and 5 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145345-95:
(8*1)+(7*4)+(6*5)+(5*3)+(4*4)+(3*5)+(2*9)+(1*5)=135
135 % 10 = 5
So 145345-95-5 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.
