82188-83-8 Usage

Uses

(9E)-12-Hydroxy-9-octadecenoic Acid, is an unsaturated omega-9 trans fatty acid.

Check Digit Verification of cas no

The CAS Registry Mumber 82188-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,1,8 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82188-83:
(7*8)+(6*2)+(5*1)+(4*8)+(3*8)+(2*8)+(1*3)=148
148 % 10 = 8
So 82188-83-8 is a valid CAS Registry Number.

Alkylaluminium Dichloride Induced Friedel-Crafts Acylation of Unsaturated Carboxylic Acids and Alcohols

Metzger, Juergen O.,Biermann, Ursula

, p. 645 - 650 (2007/10/02)

The ethylaluminium dichloride induced Friedel-Crafts acylation of unsaturated carboxylic acids, for example 10-undecenoic acid (1a) and oleic acid (5a), and of the respective alcohols 1b and 5b with acyl chlorides and cyclic acyl anhydrides gave the corresponding long-chain β,γ-unsaturated ketones 3, 6/7, 11 and 13/14 with ω-carboxy and ω-hydroxy functions, respectively.The intramolecular cyclization of petroselinic acid chloride (17) yielded (E)-2-dodecylidenecyclohexanone (18).Catalytic hydrogenation gave the respective saturated ketones 4, 8/9, 12, 15/16 and 19.Key Words: Friedel-Crafts acylation / β,γ-Unsaturated keto carboxylic acids and alcohols
