123200-21-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123200-21-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,2,0 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 123200-21:
(8*1)+(7*2)+(6*3)+(5*2)+(4*0)+(3*0)+(2*2)+(1*1)=55
55 % 10 = 5
So 123200-21-5 is a valid CAS Registry Number.

Preparative scale syntheses of isomerically pure (10E,12E,14Z)- and (10E,12E,14E)-hexadeca-10,12,14-trienals, sex pheromone components of Manduca sexta

Chen, Xin,Millar, Jocelyn G.

, p. 113 - 118 (2000)

Short, efficient syntheses yielding products of very high isomeric purity have been developed for (10E,12E,14Z)-hexadeca-10,12,14-trienal 1 and the (10E,12E,14E)-isomer 2, the key pheromone components of the tobacco hornworm moth Manduca sexta. The penultimate (EEZ)-trienol, and aldehyde 1, were freed from isomeric impurities by selective reaction of the impurities with tetracyanoethylene. (EEE)-Aldehyde 2 was prepared by Wittig reaction of (2E,4E)-hexa-2,4-dienyltriphenylphosphonium bromide with 10-acetoxydecanal, deprotection, selective crystallization of the (EEE)-trienol from the resulting mix of isomers, and oxidation. The yield of the (EEE)-trienol was increased further by iodine-catalyzed isomerization of the mix of isomers in the liquor, and further recrystallization.
