Check Digit Verification of cas no
The CAS Registry Mumber 136539-81-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,5,3 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 136539-81:
(8*1)+(7*3)+(6*6)+(5*5)+(4*3)+(3*9)+(2*8)+(1*1)=146
146 % 10 = 6
So 136539-81-6 is a valid CAS Registry Number.

Studies related to fatty acid desaturation. Part I: Preparation of methyl-substituted nonanols, nonyl bromides and total synthesis of new branched oleic acids
Genard, S.,Patin, H.
, p. 397 - 406 (2007/10/02)
Convenient pathways for the synthesis of seven structurally defined isomers of methyl-nonanols and methyl-nonylbromides are described.These synthons are used to perform Wittig reactions between convenient phosphoranes and aldehydes in order to obtain seven new octadecenoic acids bearing a methyl grouping on carbons 11 to 17. branched nonan-1-ols / branched 1-nonylbromides / Wittig reactions / methyl 9-bromononanoate / methyl 8-formyloctanoate / methyl 11 or 17-methyloctadec-9-enoates
