β-Phenyl-β-chloroethyldichlorophosphine, also known as 2-chloro-2-phenylethyl dichlorophosphine, is an organophosphorus compound with the chemical formula C8H8Cl3P. It is a colorless to pale yellow liquid with a pungent odor and is used as a chemical warfare agent, specifically as a nerve agent. β-phenyl-β-chloroethyldichlorophosphine inhibits the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system and causing severe physiological effects. It is highly toxic and can be absorbed through the skin, inhalation, or ingestion, posing a significant risk to human health and the environment. Due to its potential use in chemical warfare, it is strictly regulated under various international conventions.
The CAS Registry Mumber 66441-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,4,4 and 1 respectively; the second part has 2 digits, 5 and 0 respectively. Calculate Digit Verification of CAS Registry Number 66441-50: (7*6)+(6*6)+(5*4)+(4*4)+(3*1)+(2*5)+(1*0)=127 127 % 10 = 7 So 66441-50-7 is a valid CAS Registry Number.
