Methyl α,α-dichloro-β-(4-chlorophenyl)propionate, also known as dichlofenthion, is an organophosphorus compound that functions as an insecticide and acaricide. It is used to control a variety of pests, including insects and mites, in agricultural settings. The chemical is characterized by its ability to inhibit the enzyme acetylcholinesterase, which is crucial for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately the death of the target pests. Dichlofenthion is known for its effectiveness against a broad spectrum of pests and is used in the protection of crops such as cotton, fruits, and vegetables. However, due to its potential environmental and health risks, its use is regulated in many countries, and alternative, less harmful pesticides are often preferred.

Check Digit Verification of cas no

The CAS Registry Mumber 1552-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,5 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1552-77:
(6*1)+(5*5)+(4*5)+(3*2)+(2*7)+(1*7)=78
78 % 10 = 8
So 1552-77-8 is a valid CAS Registry Number.

Process for the arylation of olefines

-

, (2008/06/13)

A process for arylating an olefinic compound by addition of an aryl group to a double bond of said olefinic compound consisting in diazotizing an arylamine in an aqueous acidic solution comprising a lower alkanoic acid to form a solution of an aryldiazonium salt and reacting said aryldiazonium salt solution with an olefinic compound in an organic solvent in the presence of a catalytically effective amount of a copper halide. The amount of alkanoic acid is about 15 to 37% by volume of the total solvents used. The alkanoic acid is preferably acetic acid and the copper halide cuprous chloride.
