N-ethyl-N-cyclohexyl-N',N'-dimethyl-diamidophosphoryl fluoride, also known as VX, is a highly toxic organophosphorus compound that belongs to the class of chemical warfare agents. It is a colorless, odorless, and tasteless oily liquid, making it difficult to detect without specialized equipment. VX is a potent inhibitor of the enzyme acetylcholinesterase, which is crucial for the proper functioning of the nervous system. By inhibiting this enzyme, VX leads to the accumulation of acetylcholine, causing overstimulation of muscles and nerves, ultimately leading to respiratory failure and death. It is classified as a nerve agent and is considered to be one of the most toxic chemicals known. Due to its extreme toxicity, VX is subject to strict international controls and is banned under the Chemical Weapons Convention.
The CAS Registry Mumber 564-74-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 4 respectively; the second part has 2 digits, 7 and 4 respectively. Calculate Digit Verification of CAS Registry Number 564-74: (5*5)+(4*6)+(3*4)+(2*7)+(1*4)=79 79 % 10 = 9 So 564-74-9 is a valid CAS Registry Number.
