1173-21-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1173-21-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,7 and 3 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1173-21:
(6*1)+(5*1)+(4*7)+(3*3)+(2*2)+(1*1)=53
53 % 10 = 3
So 1173-21-3 is a valid CAS Registry Number.

7β-HYDROXYCARDENOLIDE GLYCOSIDES
Szeleczky, Z.,Soti, M.,Horvath, Gy.,Albrecht, K.
, p. 11 - 28 (2007/10/02)
The microbial transformation of digitoxin (I) by Streptomyces sp. yielded digoxin (III) as main product along with the by-products 7β-hydroxydigitoxin (II) and 7β-hydroxydigoxin (IV).The present paper is concerned with the structure elucidation of 7β-hydroxycardenolides as well as with the formation of some of their derivatives.
