Check Digit Verification of cas no
The CAS Registry Mumber 10204-66-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,0 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 10204-66:
(7*1)+(6*0)+(5*2)+(4*0)+(3*4)+(2*6)+(1*6)=47
47 % 10 = 7
So 10204-66-7 is a valid CAS Registry Number.

Partial Synthesis of Cardenolides and Cardenolide Analogues. XI. Synthesis of 3-(3&β,14-Dihydroxy-5&β,14&β-androstan-17&β-yl-methyl)but-2-en-4-olide, a Homologous 5&β,14&β-Cardenolide

Wittig reaction of 3β,14-dihydroxy-5β,14β-androstane-17β-carboxaldehyde 4 with 2-carboxy-1-ethoxycarbonyl-ethyl-triphenylphosphorane 11 followed by the reduction of the resulting half ester 5 and cyclization of the γ-hydroxy acid 6 yields the 3-alkylidenebutan-4-olide 8a which was isomerized to the 3-(steroidylmethyl)but-2-en-4-olide 9.Insertion of the methylene group between the steroidyl moiety and the but-2-en-4-olide ring strongly reduces the biological activity.
