15516-38-8 Usage
General Description
Phosphonic acid, bis(2-methylphenyl) ester is a chemical compound commonly used as an intermediate in the production of agrochemicals and pharmaceuticals. It is a derivative of phosphorous acid and consists of two methylphenyl groups attached to the phosphorus atom. Phosphonic acid, bis(2-methylphenyl) ester is often employed as a stabilizer and flame retardant in polymers and plastics due to its high thermal stability and excellent resistance to heat and flame. It is also used as a cross-linking agent for natural and synthetic rubber, as well as a chelating agent in metal cleaning and treatment processes. However, it is important to handle this compound with caution as it can be harmful if ingested, inhaled, or absorbed through the skin, and can cause irritation to the eyes and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 15516-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,1 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 15516-38:
(7*1)+(6*5)+(5*5)+(4*1)+(3*6)+(2*3)+(1*8)=98
98 % 10 = 8
So 15516-38-8 is a valid CAS Registry Number.
