N-Di-m-toluidinophosphono-dichloressigsaeureamid, also known as N,N-dimethyl-3-methylphenyl phosphorodichloridate or DMMP, is an organophosphorus compound with the chemical formula C9H12Cl2NO2P. It is a colorless, oily liquid with a pungent odor and is used as a chemical warfare agent. DMMP is a simulant for the more toxic and persistent nerve agent VX, and it is often used in military training exercises to mimic the effects of VX exposure. The compound is highly toxic and can cause severe health issues, including respiratory failure, seizures, and death. Due to its potential use in chemical warfare, DMMP is regulated under the Chemical Weapons Convention.
The CAS Registry Mumber 5171-22-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,7 and 1 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 5171-22: (6*5)+(5*1)+(4*7)+(3*1)+(2*2)+(1*2)=72 72 % 10 = 2 So 5171-22-2 is a valid CAS Registry Number.
