O-ethyl phosphorodifluoridothioate, also known as ethyl difluorothiophosphate or DFP, is a highly toxic organophosphorus compound with the chemical formula C2H5F2PS. It is a colorless, oily liquid with a faint, garlic-like odor. DFP is a potent inhibitor of the enzyme acetylcholinesterase, which plays a crucial role in the nervous system by breaking down the neurotransmitter acetylcholine. Inhibition of this enzyme leads to an accumulation of acetylcholine, causing overstimulation of the nervous system and potentially leading to severe health issues or death. Due to its toxicity, DFP has been used as a chemical warfare agent and as a pesticide. However, its use in warfare has been banned under the Chemical Weapons Convention, and its use as a pesticide has been restricted or discontinued in many countries due to its high toxicity and potential for human exposure.

460-53-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 460-53-7 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, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 460-53:
(5*4)+(4*6)+(3*0)+(2*5)+(1*3)=57
57 % 10 = 7
So 460-53-7 is a valid CAS Registry Number.
