889451-98-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 889451-98-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,4,5 and 1 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 889451-98:
(8*8)+(7*8)+(6*9)+(5*4)+(4*5)+(3*1)+(2*9)+(1*8)=243
243 % 10 = 3
So 889451-98-3 is a valid CAS Registry Number.

Synthesis and properties of several isomers of the cardioactive steroid ouabain
Hong, Bor-Cherng,Kim, Seongkon,Kim, Tae-Seong,Corey
, p. 2711 - 2715 (2006)
The ouabain isomers 1, 6, 20, 21, and 22 have been synthesized and shown to be readily separable by HPLC, which indicates that they do not correspond to a putative endogenous ouabain-like cardioregulator. 11-epi-Ouabain (1) is of interest as a safer alter
