N-methoxy-2-methyl-2-propenamide, also known as methomyl, is a synthetic organophosphorus compound primarily used as an insecticide. It is a white crystalline solid with the chemical formula C5H10N2O2S. Methomyl works by inhibiting the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects. This inhibition leads to an accumulation of acetylcholine, causing overstimulation and ultimately death of the target pests. The compound is effective against a wide range of insects, including aphids, whiteflies, and various types of caterpillars. Methomyl is used in agriculture to protect crops from damage caused by these pests, but it is also known for its high toxicity to humans and the environment, which has led to its restricted use in some countries.
The CAS Registry Mumber 2231-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,3 and 1 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 2231-77: (6*2)+(5*2)+(4*3)+(3*1)+(2*7)+(1*7)=58 58 % 10 = 8 So 2231-77-8 is a valid CAS Registry Number.
