173655-56-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 173655-56-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,3,6,5 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 173655-56:
(8*1)+(7*7)+(6*3)+(5*6)+(4*5)+(3*5)+(2*5)+(1*6)=156
156 % 10 = 6
So 173655-56-6 is a valid CAS Registry Number.

Absolute stereostructures of novel cytotoxic metabolites, penostatins A- E, from a Penicillium species separated from an Enteromorpha alga
Iwamoto, Chika,Minoura, Katsuhiko,Oka, Toshihide,Ohta, Takatoshi,Hagishita, Sanji,Numata, Atsushi
, p. 14353 - 14368 (1999)
Penostatins A - E have been isolated from a strain of Penicillium sp. originally separated from the marine alga Enteromorpha intestinalis, and their absolute stereostructures and confirmations have been established on the basis of spectral analyses and so
