3416-74-8 Usage
General Description
1-Chloro-4-nonyne is a chemical compound that belongs to the class of alkynes, containing a chlorine substitution on the first carbon of a nine-carbon chain. It is primarily used as a versatile building block in organic synthesis, serving as a starting material for the synthesis of various pharmaceuticals, agrochemicals, and other fine chemicals. 1-Chloro-4-nonyne is known for its reactivity as an electrophile in many chemical reactions due to the presence of the alkyne group and the electron-withdrawing effect of the chlorine atom. It is important to handle 1-Chloro-4-nonyne with care, as it can be hazardous to health and the environment, and proper safety measures should be taken when working with this compound.
Check Digit Verification of cas no
The CAS Registry Mumber 3416-74-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,1 and 6 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 3416-74:
(6*3)+(5*4)+(4*1)+(3*6)+(2*7)+(1*4)=78
78 % 10 = 8
So 3416-74-8 is a valid CAS Registry Number.

Kolbe Synthesis of Unsaturated Pheromones by Coelectrolysis with 5-Alkynoic Acids
Seidel, Wolfgang,Schaefer, Hans J.
, p. 3898 - 3903 (2007/10/02)
The alkynoic acids 5a - g are synthesized by coelectrolysis of 5-alkynoic acids 2a - c with dicarboxylic monoesters 3a - d.By reduction, Lindlar-hydrogenation, and acetylation these are converted into pheromones such as (Z)-11-hexadecenyl acetate (7b), the pheromone of Mamestra brassicae. 2a - c can be prepared by alkynylation of 1-bromo-3-chloropropane to 1a - c, substitution by cyanide and hydrolysis.
