Phosphinic acid, ethyl-, ethyl ester, also known as ethyl phosphinate, is an organophosphorus compound with the chemical formula C4H11O2P. It is a colorless liquid with a mild, fruity odor and is soluble in water. Phosphinic acid, ethyl-, ethyl ester is primarily used as a flame retardant, plasticizer, and intermediate in the synthesis of various organophosphorus compounds. Ethyl phosphinate is also employed as a stabilizer for halogenated hydrocarbons and as a catalyst in the production of polyurethane foams. Due to its potential health and environmental risks, it is essential to handle this chemical with proper safety measures and dispose of it according to regulations.

998-80-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 998-80-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 998-80:
(5*9)+(4*9)+(3*8)+(2*8)+(1*0)=121
121 % 10 = 1
So 998-80-1 is a valid CAS Registry Number.
