Phosphonic difluoride, butyl-, also known as butylphosphonic difluoride, is an organophosphorus compound with the chemical formula C4H10FO2P. It is a colorless liquid with a pungent odor and is soluble in water. Phosphonic difluoride, butyl- is primarily used as a flame retardant, particularly in plastics, textiles, and other materials, due to its ability to release phosphorus-containing compounds that interrupt the combustion process. It is also employed as a catalyst in various chemical reactions and as an intermediate in the synthesis of other phosphorus-containing compounds. However, due to its potential health and environmental risks, including toxicity and persistence, its use is subject to strict regulations and is being phased out in some applications in favor of safer alternatives.

690-97-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 690-97-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,9 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 690-97:
(5*6)+(4*9)+(3*0)+(2*9)+(1*7)=91
91 % 10 = 1
So 690-97-1 is a valid CAS Registry Number.
