Phosphoric acid diethyl 5,5,5-trichloropentyl ester, also known as trichlorfon, is an organophosphorus compound widely used as an insecticide and acaricide. It is a colorless to pale yellow liquid with a molecular formula of C5H8Cl3O4P and a molecular weight of 257.44 g/mol. Trichlorfon works by inhibiting the enzyme acetylcholinesterase, which disrupts the nervous system of insects and mites, leading to their paralysis and death. It is effective against a broad range of pests, including mosquitoes, flies, lice, and ticks, and is used in various applications such as agriculture, veterinary medicine, and public health. Due to its potential health and environmental risks, trichlorfon is subject to strict regulations and is being phased out in some countries.
The CAS Registry Mumber 682-70-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,8 and 2 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 682-70: (5*6)+(4*8)+(3*2)+(2*7)+(1*0)=82 82 % 10 = 2 So 682-70-2 is a valid CAS Registry Number.
