Check Digit Verification of cas no

The CAS Registry Mumber 26817-65-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,1 and 7 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26817-65:
(7*2)+(6*6)+(5*8)+(4*1)+(3*7)+(2*6)+(1*5)=132
132 % 10 = 2
So 26817-65-2 is a valid CAS Registry Number.

A SIMPLE SYNTHESIS OF HENEICOS-6Z-EN-1-ONE - THE SEX PHEROMONE OF Orgyia pseudotsugata

Sokolovskaya, S. V.

, p. 86 - 87 (1980)

A method is proposed for synthesizing the insect sex pheromone heneicos-6Z-en-11-one and its homolog eicos-6Z-en-11-one.

Use of organoboranes in the synthesis of pheromones: A convenient synthesis of (Z)-6-heneicosen-11-one and (Z)-5-undecen-2-one, pheromones from the Douglas Fir Tussock Moth and the Bontebok, respectively

White,Whiteley

, p. 1141 - 1144 (2007/10/02)

Treatment of thexylborane with a halomagnesiumdialkylcuprate afforded the corresponding (R-alkyl)thexylborane in favourable yields. A second reaction with a halomagnesiumdialkenylcuprate produced the totally mixed (R-alkyl)(E-alkenyl)thexylborane. Subsequent treatment with sodium cyanide and benzoyl chloride followed by alkaline peroxide yielded an unsaturated ketone. In this way, (Z)-6-heneicosen-11-one, a sex pheromone of the Douglas Fir Tussock Moth, and (Z)-5-undecen-2-one, a pheromone from the pedal gland of the Bontebok, were prepared.

A Convenient Method for the Synthesis of Acyclic Ketones. Synthesis of Sex Pheromone of Douglas Fir Tussock Moth

Murata, Yasue,Inomata, Katsuhiko,Kinoshita, Hideki,Kotake, Hiroshi

, p. 2539 - 2540 (2007/10/02)

(α-Alkyl-α-methylthio)alkyl p-tolyl sulfones derived from the reaction of a-alkylated alkyl p-tolyl sulfones with dimethyl disulfide could be easily hydrolyzed by CuCl2-SiO2 to give the corresponding ketones in fairly good yields.This method was applied to the synthesis of Douglas Fir Tussock Moth Pheromone.
