Monothiophosphorsaeure-O,O-dimethylester-S-<3-chlor-phenylester>, also known as O,O-dimethyl S-(3-chlorophenyl) monothiophosphate, is an organophosphorus compound with the chemical formula C8H9ClO3PS. It is a colorless to pale yellow liquid with a pungent odor. Monothiophosphorsaeure-O,O-dimethylester-S-<3-chlor-phenylester> is primarily used as an insecticide and acaricide, targeting a wide range of pests in agriculture. It works by inhibiting the activity of acetylcholinesterase, an enzyme essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately paralysis and death of the target pests. Due to its toxicity, it is crucial to handle this chemical with care and follow proper safety measures to minimize risks to human health and the environment.
The CAS Registry Mumber 4184-60-5 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 0 respectively. Calculate Digit Verification of CAS Registry Number 4184-60: (6*4)+(5*1)+(4*8)+(3*4)+(2*6)+(1*0)=85 85 % 10 = 5 So 4184-60-5 is a valid CAS Registry Number.
