Diethyl-N-methoxyphosphamide, also known as methamidophos, is an organophosphorus compound that belongs to the class of pesticides, specifically acting as an insecticide and acaricide. It is a colorless, oily liquid with a slight odor and is used to control a variety of pests, including insects and mites, in agricultural settings. The chemical has a molecular formula of C4H12NO3PS and is known for its high toxicity, which necessitates careful handling and use. Due to its potential health risks and environmental concerns, methamidophos has been banned or restricted in many countries. It works by inhibiting the enzyme acetylcholinesterase in the nervous system of pests, leading to their paralysis and death. However, it is also highly toxic to mammals, including humans, and can cause severe health issues upon exposure.
The CAS Registry Mumber 1774-95-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,7 and 4 respectively; the second part has 2 digits, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1774-95: (6*1)+(5*7)+(4*7)+(3*4)+(2*9)+(1*5)=104 104 % 10 = 4 So 1774-95-4 is a valid CAS Registry Number.
