24533-02-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24533-02-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,5,3 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24533-02:
(7*2)+(6*4)+(5*5)+(4*3)+(3*3)+(2*0)+(1*2)=86
86 % 10 = 6
So 24533-02-6 is a valid CAS Registry Number.

Partial Syntheses of Cardenolides and Cardenolide Analogues. X. Synthesis of 22-O-Substituted Cardenolides and Studies on the Oxidative Degradation of Cardenolides with Potassium Permanganate

Lindig, Claus

, p. 682 - 694 (2007/10/02)

The stereoisomeric 20,22-dihydroxy-cardanolides 2a and 3a as well as the oxalic acid half ester of the 3β-acetoxy-14,21-dihydroxy-5β,14β-pregnan-20-one (4a) and 3β-acetoxy-20-oxo-5β,14β-pregnane-21,14-lactone (5) were identified as intermediates of intermediates of oxidative degradation of digitoxigenin 3-acetate with potassium permanganate. 2a and 3a, after selective acylation in 22-position, were converted to the 22-acyloxy-cardenolides 7a and 7b via dehydration or acetoxyelimination after selective acetylation of the 20-hydroxy group.Saponification of both 7a and 7b yields the very stable 22-hydroxycardenolide 8a.The molecular biological activities of the 22-substituted cardenolides were investigated and discussed.
