O-Ethyl O-methyl S-[(methylcarbamoyl)methyl] phosphorodithioate, also known as methamidophos, is an organophosphorus compound that belongs to the class of phosphorodithioate pesticides. It is a potent, broad-spectrum insecticide and acaricide, widely used in agriculture to control a variety of pests, including insects and mites. Methamidophos works by inhibiting the enzyme acetylcholinesterase, which disrupts the nervous system of the target pests, leading to their paralysis and eventual death. Due to its high toxicity to humans and the environment, methamidophos has been banned or restricted in many countries. It is important to handle this chemical with extreme caution and follow proper safety measures to minimize risks to human health and the environment.
The CAS Registry Mumber 3547-35-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,5,4 and 7 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3547-35: (6*3)+(5*5)+(4*4)+(3*7)+(2*3)+(1*5)=91 91 % 10 = 1 So 3547-35-1 is a valid CAS Registry Number.
