4,4-bis(4-hydroxyphenyl)pentanamide, also known as bisphenol A diglycidyl ether (BADGE), is a chemical compound with the molecular formula C21H24O4. It is a type of epoxy resin, which is widely used in the production of various coatings, adhesives, and composite materials due to its excellent adhesion, flexibility, and chemical resistance properties. BADGE is synthesized by reacting bisphenol A with epichlorohydrin, resulting in a diglycidyl ether structure. While it has numerous industrial applications, concerns have been raised regarding its potential health and environmental impacts, as it can release bisphenol A, a known endocrine disruptor. As a result, there is ongoing research and debate about the safety of BADGE and its alternatives in consumer products.

3442-37-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3442-37-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,4,4 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3442-37:
(6*3)+(5*4)+(4*4)+(3*2)+(2*3)+(1*7)=73
73 % 10 = 3
So 3442-37-3 is a valid CAS Registry Number.
