Check Digit Verification of cas no

The CAS Registry Mumber 98973-45-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,9,7 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98973-45:
(7*9)+(6*8)+(5*9)+(4*7)+(3*3)+(2*4)+(1*5)=206
206 % 10 = 6
So 98973-45-6 is a valid CAS Registry Number.

Fungus Pigments, 40. Leprocybin, the Fluorescent Principle of Cortinarius cotoneus and related Leprocybes (Agaricales)

Kopanski, Lothar,Klaar, Manfred,Steglich, Wolfgang

, p. 1280 - 1296 (2007/10/02)

Leprocybin (1), a glucoside responsible for the yellow-green fluorescence of the fruiting bodies under UV light has been isolated from Cortinarius toadstools (subgenus Leprocybe, section Leprocybe Mos.).On acid hydrolysis or action of β-glucosidase 1 was split into its aglycone leprocyboside (6), the constitution of which was elucidated by several derivatisations, decarboxylation to 10, and alkaline degradation.Final structural proof of the pyranoxanthone system was obtained by synthesis of 8-O-methyl(decarboxy)leprocyboside (12).
