Check Digit Verification of cas no

The CAS Registry Mumber 145476-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,4,7 and 6 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 145476-95:
(8*1)+(7*4)+(6*5)+(5*4)+(4*7)+(3*6)+(2*9)+(1*5)=155
155 % 10 = 5
So 145476-95-5 is a valid CAS Registry Number.

New polyhydroxylated cholestane glycosides from the Bulbs of Ornithogalum saundersiae

Kubo,Mimaki,Sashida,Nikaido,Ohmoto

, p. 2469 - 2472 (1992)

Fresh bulbs of Ornithogalum saundersiae were found to contain five new polyhydroxylated cholestane glycosides. Their structures were determined to be (22S)-cholest-5-ene-3β,11β,16β,22-tetrol 16-O-α-L-rhamnopyranoside (1) and its acetyl derivatives (2 and 3), and (22S)-cholesta-5,24-diene-3β,11β,16β,22-tetrol 16-O-α-L-rhamnopyranoside (4) and its acetyl derivative (5) using spectroscopic analysis and chemical correlations. Determination of the absolute configuration at the C-22 hydroxyl position of 1 was achieved by the application of the advanced Mosher's method to the aglycon (1a) of 1, and those of 2-5 by correlating them to 1. The cholestane glycosides with an acetyl group at the C-3 hydroxyl position of the rhamnose showed potent inhibitory activity on cyclic adenosine monophosphate (AMP) phosphodiesterase.
