Monothiophosphorsaeure-O,O-dimethylester-S-<2,5-dichlor-phenylester>, also known as O,O-dimethyl monothiophosphoric acid S-(2,5-dichlorophenyl) ester, is an organophosphorus compound with the chemical formula C9H9Cl2O3PS. It is a colorless to pale yellow liquid with a pungent odor. Monothiophosphorsaeure-O,O-dimethylester-S-<2,5-dichlor-phenylester> is primarily used as an insecticide and acaricide in agriculture, targeting pests such as aphids, mites, and whiteflies. It works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. Due to its effectiveness and low mammalian toxicity, it is widely used in various crops to protect against damage caused by these pests. However, it is important to follow proper safety measures and guidelines when handling and applying this chemical to minimize potential risks to human health and the environment.
The CAS Registry Mumber 4184-62-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,8 and 4 respectively; the second part has 2 digits, 6 and 2 respectively. Calculate Digit Verification of CAS Registry Number 4184-62: (6*4)+(5*1)+(4*8)+(3*4)+(2*6)+(1*2)=87 87 % 10 = 7 So 4184-62-7 is a valid CAS Registry Number.
