2,2-bis-(4-methoxy-phenyl)-3-methyl-butane, also known as bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C23H26O4. It is a colorless, viscous liquid that is widely used as a component in epoxy resins, particularly in the production of food and beverage cans. BADGE is known for its ability to form strong, stable polymers, which contribute to the protective lining of these cans. However, it has been a subject of concern due to potential health risks associated with its release into the environment and possible migration into food products. As a result, there has been ongoing research and debate regarding its safety and the development of alternative materials.
The CAS Registry Mumber 5716-77-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,1 and 6 respectively; the second part has 2 digits, 7 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5716-77: (6*5)+(5*7)+(4*1)+(3*6)+(2*7)+(1*7)=108 108 % 10 = 8 So 5716-77-8 is a valid CAS Registry Number.
