1,1-bis-(3,4-diethoxy-phenyl)-ethane, also known as bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C24H30O6. It is a colorless, viscous liquid that is widely used in the production of epoxy resins, which are essential components in various applications such as coatings, adhesives, and composite materials. BADGE is synthesized by reacting bisphenol A with epichlorohydrin in the presence of a catalyst. It is known for its excellent adhesion properties, chemical resistance, and thermal stability, making it a valuable additive in the manufacturing of epoxy-based products. However, it is important to note that bisphenol A, a component of BADGE, has been a subject of concern due to potential health and environmental risks, leading to regulations and restrictions on its use in certain applications.
The CAS Registry Mumber 5385-73-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,8 and 5 respectively; the second part has 2 digits, 7 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5385-73: (6*5)+(5*3)+(4*8)+(3*5)+(2*7)+(1*3)=109 109 % 10 = 9 So 5385-73-9 is a valid CAS Registry Number.
