Chloridothiophosphoric acid O-(2,4-dichlorophenyl)O-methyl ester, also known as methyl 2,4-dichlorophenyl chlorothionophosphate, is an organophosphorus compound with the chemical formula C7H6Cl3O3PS. It is a colorless to pale yellow liquid with a pungent odor. Chloridothiophosphoric acid O-(2,4-dichlorophenyl)O-methyl ester is primarily used as an insecticide and acaricide in agriculture, targeting a wide range of pests such as aphids, mites, and caterpillars. It works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. Due to its high toxicity, it is crucial to handle this chemical with extreme care and follow proper safety measures to minimize risks to human health and the environment.
The CAS Registry Mumber 946-04-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 6 respectively; the second part has 2 digits, 0 and 4 respectively. Calculate Digit Verification of CAS Registry Number 946-04: (5*9)+(4*4)+(3*6)+(2*0)+(1*4)=83 83 % 10 = 3 So 946-04-3 is a valid CAS Registry Number.
