Methylphosphonic acid ethyl ester cyclohexylester, also known as cyclohexyl methylphosphonofluoridate, is a chemical compound with the molecular formula C7H14FO2P. It is a colorless, oily liquid that is soluble in organic solvents. Methylphosphonsaeure-ethylester-cyclohexylester is a derivative of methylphosphonic acid, where the hydroxyl group is replaced by an ethyl ester and a cyclohexyl ester group. It is primarily used as a chemical warfare agent, specifically a nerve agent, due to its ability to inhibit the enzyme acetylcholinesterase, leading to the accumulation of acetylcholine in the nervous system and causing severe physiological effects. It is important to note that handling and use of such chemicals are strictly regulated due to their potential的危害 and require specialized knowledge and safety measures.
The CAS Registry Mumber 7040-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,0,4 and 0 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 7040-55: (6*7)+(5*0)+(4*4)+(3*0)+(2*5)+(1*5)=73 73 % 10 = 3 So 7040-55-3 is a valid CAS Registry Number.
