Methylphosphonic acid mono-(2,4,5-trichlorophenyl) ester, also known as MPA-TCP, is a chemical compound derived from methylphosphonic acid and 2,4,5-trichlorophenol. It is an organophosphorus compound with the molecular formula C7H6Cl3O3P. Methylphosphonsaeure-mono-<2,4,5-trichlor-phenylester> is a toxic substance and has been associated with the degradation of certain chemical warfare agents, such as sarin. Due to its potential hazardous nature, it is crucial to handle and dispose of MPA-TCP with extreme caution, following proper safety protocols and regulations.
The CAS Registry Mumber 3935-31-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 3935-31: (6*3)+(5*9)+(4*3)+(3*5)+(2*3)+(1*1)=97 97 % 10 = 7 So 3935-31-7 is a valid CAS Registry Number.
