2,2-Bis-(4-hydroxy-phenyl)-propan-bis-(1,1,2-trifluor-2-chlor-ethylether), also known as Bisphenol A diglycidyl ether (BADGE), is a complex organic compound with the chemical formula C21H20F6O4. 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 and prevent corrosion. However, due to concerns over potential health risks associated with bisphenol A (BPA), a monomer that can leach from BADGE-based materials, there has been a growing interest in finding alternative materials. Despite these concerns, BADGE remains an important chemical in the manufacturing industry due to its versatility and effectiveness in creating durable coatings and adhesives.
The CAS Registry Mumber 1549-05-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 9 respectively; the second part has 2 digits, 0 and 5 respectively. Calculate Digit Verification of CAS Registry Number 1549-05: (6*1)+(5*5)+(4*4)+(3*9)+(2*0)+(1*5)=79 79 % 10 = 9 So 1549-05-9 is a valid CAS Registry Number.
