Check Digit Verification of cas no

The CAS Registry Mumber 92957-59-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,5 and 7 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92957-59:
(7*9)+(6*2)+(5*9)+(4*5)+(3*7)+(2*5)+(1*9)=180
180 % 10 = 0
So 92957-59-0 is a valid CAS Registry Number.

IDENTIFICATION AND DETERMINATION OF 16-CARBON 2,5-DIALKYLOXOLANES IN AUTOXIDIZED n-HEXADECANE SAMPLES BY CAPILLARY GAS CHROMATOGRAPHY AND MASS SPECTROMETRY.

Zinbo,Jensen

, p. 315 - 319 (2007/10/02)

Identification and determination of isomeric 16-carbon (C//1//6) 2,5-dialkyloxolanes, formed during the autoxidation of n-hexadecane under reduced oxygen pressures, by gas chromatography/mass spectrometry (GC/MS) and capillary GC are described. A bonded phase fused silica capillary column and a 'reduced pressure' on-column injection technique have been utilized for the quantitative GC analysis. Nine chromatographic peaks have been identified and assigned to six pairs of geometric isomers of C//1//6 2,5-dialkyloxolanes based on relative retention times, stereochemistry of cis and trans isomers, and formation of characteristic five-membered ring oxonium ions formed by electron-impact fragmentation.
