Phosphoric acid dimethylpentachlorophenyl ester, also known as dimethyl pentachlorophenyl phosphate, is a chemical compound with the molecular formula C8H7Cl5O4P. It is an organophosphorus compound derived from phosphoric acid, where two methyl groups and a pentachlorophenyl group are attached to the phosphorus atom. Phosphoric acid dimethylpentachlorophenyl ester is primarily used as an insecticide and acaricide, targeting pests such as mites and ticks in agriculture. Due to its chemical structure, it exhibits neurotoxic effects on insects by inhibiting the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine and subsequent paralysis and death of the target organisms. However, it is important to note that the use of such chemicals should be managed carefully due to their potential environmental and health impacts.
The CAS Registry Mumber 957-84-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,5 and 7 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 957-84: (5*9)+(4*5)+(3*7)+(2*8)+(1*4)=106 106 % 10 = 6 So 957-84-6 is a valid CAS Registry Number.
