1,1-difluoroethyl fluorosulfate, also known as DF, is a highly toxic organofluorophosphorus compound with the chemical formula C2H2F3O2S. It is a colorless, oily liquid that is soluble in organic solvents and has a pungent odor. DF is a potent and irreversible inhibitor of the enzyme acetylcholinesterase, which plays a crucial role in the nervous system by breaking down the neurotransmitter acetylcholine. As a result, exposure to DF leads to the accumulation of acetylcholine, causing overstimulation of the nervous system and potentially leading to seizures, respiratory failure, and death. Due to its high toxicity, DF has been classified as a chemical warfare agent and is subject to strict regulations and controls. It is important to handle and store DF with extreme caution, as even small amounts can pose a significant risk to human health and the environment.
The CAS Registry Mumber 460-95-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,6 and 0 respectively; the second part has 2 digits, 9 and 5 respectively. Calculate Digit Verification of CAS Registry Number 460-95: (5*4)+(4*6)+(3*0)+(2*9)+(1*5)=67 67 % 10 = 7 So 460-95-7 is a valid CAS Registry Number.
