Uses

Used in Plastics Industry:
Bisphenol A is used as a key component in the production of epoxy resins and polycarbonate plastics for its ability to enhance the durability, heat resistance, and transparency of the materials. It is commonly found in various consumer products, including food containers, water bottles, and dental sealants.
Used in Coatings Industry:
In the coatings industry, bisphenol A is utilized as a curing agent for epoxy resins, providing improved adhesion, chemical resistance, and mechanical properties to the coatings. It is particularly useful in applications requiring high-performance coatings, such as automotive, aerospace, and electronics industries.
Used in Electrical and Electronic Industry:
Bisphenol A is employed in the electrical and electronic industry as a component of insulating materials, circuit boards, and connectors. Its properties, such as heat resistance and flame retardancy, make it suitable for applications where high reliability and safety are required.
However, due to the potential health risks associated with bisphenol A, there has been a growing trend towards the development and use of alternative materials and compounds that do not possess endocrine-disrupting properties. Regulatory bodies and industries are increasingly focusing on safer alternatives to minimize the exposure to bisphenol A and its potential adverse effects on human health and the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 5394-98-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 4 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5394-98:
(6*5)+(5*3)+(4*9)+(3*4)+(2*9)+(1*8)=119
119 % 10 = 9
So 5394-98-9 is a valid CAS Registry Number.
