1,1-Bis-<4-(3-hydroxy-3-methyl-butyl)-phenyl>-ethan, also known as Bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C25H34O4. It is a colorless, viscous liquid that is widely used as a component in epoxy resins, particularly in the production of food and beverage can linings, due to its ability to provide a protective barrier against corrosion and contamination. BADGE is formed by the reaction of bisphenol A (BPA) with epichlorohydrin, resulting in a molecule that contains two phenolic groups connected by an ethyl bridge. While it plays a crucial role in the manufacturing of protective coatings, there has been ongoing debate and research regarding the potential health and environmental impacts of BPA and its derivatives, including BADGE, due to concerns about endocrine disruption and other potential effects.
The CAS Registry Mumber 1767-73-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,7,6 and 7 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 1767-73: (6*1)+(5*7)+(4*6)+(3*7)+(2*7)+(1*3)=103 103 % 10 = 3 So 1767-73-3 is a valid CAS Registry Number.
