1,9-Bis-(4-amino-2-chlorphenoxy)nonane, also known as BADGE, is a chemical compound with the molecular formula C21H26Cl2N2O2. It is a type of epoxy resin curing agent, commonly used in the production of plastic materials, particularly in the manufacturing of epoxy-based composites and coatings. BADGE is known for its ability to improve the mechanical properties and chemical resistance of the final product. However, it has also raised concerns due to the potential release of harmful substances, such as bisphenol A (BPA) and chlorinated phenols, during the curing process. As a result, there has been a growing interest in finding safer alternatives to BADGE in various applications.
The CAS Registry Mumber 5226-80-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,2 and 6 respectively; the second part has 2 digits, 8 and 0 respectively. Calculate Digit Verification of CAS Registry Number 5226-80: (6*5)+(5*2)+(4*2)+(3*6)+(2*8)+(1*0)=82 82 % 10 = 2 So 5226-80-2 is a valid CAS Registry Number.
