59965-19-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 59965-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,9,6 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 59965-19:
(7*5)+(6*9)+(5*9)+(4*6)+(3*5)+(2*1)+(1*9)=184
184 % 10 = 4
So 59965-19-4 is a valid CAS Registry Number.

Pheromone Synthesis, CXXVI. Synthesis and Biological Activity of Four Stereoisomers of 6,10,14-Trimethyl-2-pentadecanol, the Female-Produced Sex Pheromone of Rice Moth (Corcyra cephalonica)

Mori, Kenji,Harada, Hironori,Zagatti, Pierre,Cork, Alan,Hall, David R.

, p. 259 - 267 (2007/10/02)

The synthesis of four stereoisomers of the female-produced sex pheromone of the rice moth (Corcyra cephalonica) was achieved by starting from (R)-2a, (R)- or (S)-3a, and (R)- or (S)-4 and using alkylation of alkyl phenyl sulfones as the coupling reaction.Behavioral bioassy of each isomer revealed (2R,6R,10R)-1a to be eight times more active than a diastereomeric mixture of equal amounts of the eight possible stereoisomers, indicating that (2R,6R,10R)-1a is probably the natural pheromone or at least themajor component of the female blend.Electrophysiological bioassy also confirmed the high activity of (2R,6R,10R)-1a.
