506-21-8 Usage
Uses
Linoelaidic acid is the all-trans fatty acid homolog of linoleic acid. Trans-fatty acids are generally not detected in raw food oils, but constitute up to 25% of the unsaturated fat in partially hydrogenated oils.
Definition
ChEBI: An octadecadienoic acid containing two E (trans) double bonds at positions 9 and 12.
Check Digit Verification of cas no
The CAS Registry Mumber 506-21-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,0 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 506-21:
(5*5)+(4*0)+(3*6)+(2*2)+(1*1)=48
48 % 10 = 8
So 506-21-8 is a valid CAS Registry Number.

Method of producing dicarboxylic acids
-
Page/Page column 11; 13, (2009/05/29)
A method of producing dicarboxylic acids (e.g., α,ω dicarboxylic acids) by reacting a compound having a terminal COOH (e.g., unsaturated fatty acid such as oleic acid) and containing at least one carbon-carbon double bond with a second generation Grubbs catalyst in the absence of solvent to produce dicarboxylic acids. The method is conducted in an inert atmosphere (e.g., argon, nitrogen). The process also works well with mixed unsaturated fatty acids obtained from soybean, rapeseed, tall, and linseed oils.
