General Description
Phosphonic acid, butyl ethyl ester, also known as mono-butyl ethylphosphonate, is an organophosphorus compound with the molecular formula C6H15O3P. This chemical is commonly used as a plasticizer, flame retardant, and an intermediate in the synthesis of other chemicals. It is a colorless, odorless liquid with low solubility in water and high solubility in organic solvents. Phosphonic acid, butyl ethyl ester has been shown to exhibit strong thermal stability and resistance to hydrolysis, making it suitable for applications in various industries such as the production of plastics, rubber, and textiles. However, it is important to handle this chemical with care as it is considered hazardous if ingested, inhaled, or comes into contact with the skin or eyes.Check Digit Verification of cas no
The CAS Registry Mumber 1656-71-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 1656-71:
(6*1)+(5*6)+(4*5)+(3*6)+(2*7)+(1*1)=89
89 % 10 = 9
So 1656-71-9 is a valid CAS Registry Number.
