Check Digit Verification of cas no

The CAS Registry Mumber 127477-67-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,7 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127477-67:
(8*1)+(7*2)+(6*7)+(5*4)+(4*7)+(3*7)+(2*6)+(1*7)=152
152 % 10 = 2
So 127477-67-2 is a valid CAS Registry Number.

IDENTIFICATION OF THE BY-PRODUCTS OF ANODIC COUPLING BETWEEN ERUCIC AND PROPIONIC ACIDS AND BETWEEN OLEIC AND HEPTANOIC ACIDS, USING GAS CHROMATOGRAPHY-MASS SPECTROMETRY AND INFRARED SPECTROSCOPY

Konopski, Leszek,Polec, Iwona

, p. 409 - 422 (2007/10/02)

A method is described as the simplest way for the synthesis of (Z)-9-tricosene, the sex pheromone of the housefly.The mixture of prodicts obtained on repeating the title syntheses appeared to be much more complex than described previously.The following by-products were identified using the GC/MS method: hydrocarbons with a straight chain - saturated C8 to C23, unsaturated C13 to C24; the dienes C20 and C21; and the methyl esters of fatty acids C7 to C22 (depending on the reaction path).In the products of the anodic coupling of erucic and propionic acids considerable amounts of high-molecular compounds were formed.The non-reported new compounds with molecular weights of 584 and 614 were formed in addition to the excepted 9,33-dotetracontadiene (m.w. 586).Their structures were elucidated by mass and ir spectroscopy as 9,20,33-dotetracontatriene (m.w. 584) and 9,34-tritetracontadien-21-one (m.w. 614).Mechanism of the formation of the by-products are proposed.
