Check Digit Verification of cas no

The CAS Registry Mumber 16910-32-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,1 and 0 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 16910-32:
(7*1)+(6*6)+(5*9)+(4*1)+(3*0)+(2*3)+(1*2)=100
100 % 10 = 0
So 16910-32-0 is a valid CAS Registry Number.

The R-(−) isomer of methyl 1-(2,2-dimethylindan-1-yl) imidazole-5-carboxylate (CGA 214372; 2) strongly inhibited P450-dependent obtusifoliol 14α-demethylase (P450OBT.14DM) (I50 = 8 × 10−9M, I50Km = 5 × 10−5) in a maize (Zea mays) microsomal preparation. Kinetic studies indicated uncompetitive...detailed

The 14α-demethylation of obtusifoliol (cas 16910-32-0) by a cytochrome P-450 monooxygenase from higher plants microsomes08/10/2019

Microsomes isolated from corn embryos (Zea mays) can demethylate the 14α-methyl group of obtusifoliol 2. An enzymatic assay has been developped for obtusifoliol 14α-methyl-demethylase in higher plants. The enzymatic reaction was shown to occur sequentially, converting obtusifoliol 2 to 4α-met...detailed

Stereochemistry of C-4 demethylation during conversion of obtusifoliol (cas 16910-32-0) into poriferasterol by Ochromonas malhamensis08/09/2019

Obtusifoliol-[2,2,4-3H3] was synthesised and incubated with the chrysophyte alga Ochromonas malhamensis which converted it into poriferasterol. A reaction sequence applied to poriferasterol showed that the tritium retained at C-4 occupied the 4α-position. This demonstrates that biological C-4 d...detailed

Obtusifoliol 14α-demethylase is a plant orthologue of sterol 14α-demethylase (CYP51) essential in sterol biosynthesis. We have prepared CYP51 antisense Arabidopsis in order to shed light on the sterol and steroid hormone biosynthesis in plants. Arabidopsis putative CYP51 cDNA (AtCYP51) was obt...detailed

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

, 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.
