4741-53-1 Usage
General Description
Tetraphenylphthalic anhydride (TPPA) is a white crystalline solid chemical compound used in the production of engineering plastics, resins, and coatings. It is a key ingredient in the synthesis of high-performance polymers such as polyimides and polyesters, as well as epoxy resins. TPPA is also utilized in the manufacture of flame-retardant materials and heat-resistant coatings due to its high thermal stability and resistance to moisture, chemicals, and UV radiation. It is a versatile compound that finds application in various industries, including electronics, aerospace, automotive, and construction, due to its excellent mechanical properties and chemical resistance.
Check Digit Verification of cas no
The CAS Registry Mumber 4741-53-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,4 and 1 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4741-53:
(6*4)+(5*7)+(4*4)+(3*1)+(2*5)+(1*3)=91
91 % 10 = 1
So 4741-53-1 is a valid CAS Registry Number.
