Tris-(ethylmercapto)-essigsaeure, also known as triethyl phosphite, is an organophosphorus compound with the chemical formula (C2H5O)3P. It is a colorless, oily liquid that is soluble in organic solvents and has a pungent odor. Tris-(ethylmercapto)-essigsaeure is primarily used as a stabilizer for halogenated hydrocarbons, such as chlorofluorocarbons (CFCs), to prevent their decomposition and the formation of harmful byproducts. Additionally, triethyl phosphite is employed as a reagent in organic synthesis, particularly in the preparation of various phosphorus-containing compounds. Due to its potential health and environmental risks, it is essential to handle and store triethyl phosphite with proper safety measures.

Check Digit Verification of cas no

The CAS Registry Mumber 20532-00-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,5,3 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20532-00:
(7*2)+(6*0)+(5*5)+(4*3)+(3*2)+(2*0)+(1*0)=57
57 % 10 = 7
So 20532-00-7 is a valid CAS Registry Number.
