1,2-Bis-<4-(3-hydroxy-3-methyl-butyl)-phenyl>-ethan, also known as Bisphenol A diglycidyl ether (BADGE), is a complex organic 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 cans. BADGE is known for its ability to form strong, stable polymers that provide a protective barrier against corrosion and contamination. However, it has been a subject of concern due to potential health risks associated with its breakdown products, such as bisphenol A (BPA), which can leach into food and beverages. As a result, there has been a push towards the development of alternative materials that can offer similar properties without the associated health concerns.
The CAS Registry Mumber 1566-59-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,6 and 6 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 1566-59: (6*1)+(5*5)+(4*6)+(3*6)+(2*5)+(1*9)=92 92 % 10 = 2 So 1566-59-2 is a valid CAS Registry Number.
