N-Cyclohhexylphosphoramidothioic acid O,O-dimethyl ester, also known as O,O-dimethyl-N-cyclohexylphosphoramidothioate, is an organophosphorus compound with the chemical formula C9H18NO2PS. It is a colorless liquid with a pungent odor and is used as an insecticide and acaricide in agriculture. N-Cyclohexylphosphoramidothioic acid O,O-dimethyl ester works by inhibiting the activity of acetylcholinesterase, an enzyme responsible for breaking down the neurotransmitter acetylcholine, leading to the overstimulation of the nervous system in insects and mites. Due to its effectiveness and low mammalian toxicity, it is widely used in the control of various pests, including aphids, whiteflies, and spider mites. However, it is essential to handle this chemical with care, as it can be harmful to humans and the environment if not used properly.
The CAS Registry Mumber 941-39-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,4 and 1 respectively; the second part has 2 digits, 3 and 9 respectively. Calculate Digit Verification of CAS Registry Number 941-39: (5*9)+(4*4)+(3*1)+(2*3)+(1*9)=79 79 % 10 = 9 So 941-39-9 is a valid CAS Registry Number.
