Fluorophosphonic acid di-sec-butyl ester, also known as DF, is a colorless, oily liquid with the chemical formula C8H17F2O2P. It is a highly toxic organophosphorus compound that acts as a potent nerve agent, inhibiting the enzyme acetylcholinesterase and disrupting the nervous system. Fluorophosphonic acid di-sec-butyl ester is a Schedule 1 chemical weapon under the Chemical Weapons Convention and is considered a threat due to its potential use in chemical warfare. It is important to note that handling and possession of such chemicals are strictly regulated and controlled by international law to prevent their misuse.

625-17-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 625-17-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,2 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 625-17:
(5*6)+(4*2)+(3*5)+(2*1)+(1*7)=62
62 % 10 = 2
So 625-17-2 is a valid CAS Registry Number.

Dichlorodimethylhydantoin-KF as an efficient reagent for one pot synthesis of dialkylfluorophosphates from dialkylphosphites

Gupta,Acharya,Dubey,Kaushik

, p. 226 - 229 (2008/09/16)

Organic-inorganic hybrid reagent dichlorodimethylhydantoin-KF (DCDMH-KF) mixture was explored as an efficient reagent for the direct conversion of dialkylphosphites to their corresponding dialkylfluorophosphates at room temperature and in shorter reaction times through a facile electrophilic-nucleophilic metathesis.
