50657-31-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50657-31-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,6,5 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 50657-31:
(7*5)+(6*0)+(5*6)+(4*5)+(3*7)+(2*3)+(1*1)=113
113 % 10 = 3
So 50657-31-3 is a valid CAS Registry Number.

Synthesis of Lichesterol

Anastasia, Mario,Fiecchi, Alberto

, p. 2125 - 2126 (1981)

Ergosta-5,8(9),22-trien-3β-ol has been synthesized and its identity with lichesterol has been confirmed.Ergosteryl acetate was transformed into 7α-ergosta-5,8(9),22-trien-3β-yl acetate which was converted into lichesterol by reduction with lithium in ethylamine.

EFFECT ON ERGOSTEROL BIOSYNTHESIS OF A FUNGICIDE, SSF-109, IN BOTRYTIS CINEREA

Shirane, Noboru,Murabayashi, Akira,Masuko, Michio,Uomori, Atsuko,Yoshimura, Yohko,et al.

, p. 2513 - 2520 (2007/10/02)

Treatment of Botrytis cinerea with a novel fungicide SSF-109, (dl)-cis-1-(4-chlorophenyl)-2-(1H-1,2,4-triazol-1-yl)cyclo-heptanol (0.45 μg ml-1), gave five 14α-methyl sterols, 24-methylene-24(25)-dihydrolanosterol, 24-methylene-24(25)-dihydrolanosten-3-one, obtusifoliol, obtusifolione, and 14α-methylfecosterol, together with ergosterol and ergosta-5,8,22-trien-3β-ol.SSF-109 was found to inhibit the biosynthesis of ergosterol at the 14α-demethylation step.
