Diethyl [3-(2,4,5-trichlorophenoxy)propyl]phosphonate, also known as trichlorfon, is an organophosphorus compound that has been widely used as an insecticide and acaricide. It is a colorless, oily liquid with a slight odor and is soluble in water. Trichlorfon works by inhibiting the enzyme acetylcholinesterase, which is essential for the proper functioning of the nervous system in insects. This inhibition leads to the accumulation of acetylcholine, causing overstimulation and ultimately paralysis and death of the target pests. The chemical has been used in agriculture to control a variety of pests, including mites, aphids, and flies. However, due to its potential health risks and environmental concerns, its use has been restricted or banned in several countries. Trichlorfon is also known for its potential to contaminate water sources and its toxicity to aquatic life, which has led to increased scrutiny and regulation of its application.
The CAS Registry Mumber 6954-82-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,5 and 4 respectively; the second part has 2 digits, 8 and 2 respectively. Calculate Digit Verification of CAS Registry Number 6954-82: (6*6)+(5*9)+(4*5)+(3*4)+(2*8)+(1*2)=131 131 % 10 = 1 So 6954-82-1 is a valid CAS Registry Number.
