Methanone, (2,4-dihydroxy-1,3-phenylene)bis[phenyl-], also known as bisphenol A bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C21H20O4. It is a type of epoxy resin, which is a thermosetting polymer used in various applications such as coatings, adhesives, and composite materials. BADGE is formed by the reaction of bisphenol A (BPA) with epichlorohydrin, resulting in a molecule with two phenyl rings connected by a methylene bridge and two epoxy groups. Methanone, (2,4-dihydroxy-1,3-phenylene)bis[phenyl- is known for its high reactivity and excellent adhesion properties, making it a valuable component in the production of durable and strong materials. However, it is also important to note that bisphenol A, a precursor in the synthesis of BADGE, has been a subject of concern due to potential health and environmental impacts, leading to regulations and alternatives being sought in certain applications.

82-64-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 82-64-4 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 82-64:
(4*8)+(3*2)+(2*6)+(1*4)=54
54 % 10 = 4
So 82-64-4 is a valid CAS Registry Number.
