42423-25-6 Usage
General Description
Phenol, 4,4-methylenebis-, polymer with (chloromethyl)oxirane, commonly known as Novolac epoxy resin, is a type of synthetic thermosetting polymer that is formed by the reaction of bisphenol A and epichlorohydrin. It is commonly used in the production of adhesives, coatings, and composite materials due to its excellent chemical and heat resistance, as well as its strong adhesive properties. This polymer is valued for its high mechanical strength, low shrinkage, and good electrical insulation properties, making it suitable for a wide range of industrial applications, including electronics, aerospace, and automotive industries. However, it is important to handle and dispose of Novolac epoxy resin carefully, as it can be hazardous to human health and the environment if not managed properly.
Check Digit Verification of cas no
The CAS Registry Mumber 42423-25-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,4,2 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 42423-25:
(7*4)+(6*2)+(5*4)+(4*2)+(3*3)+(2*2)+(1*5)=86
86 % 10 = 6
So 42423-25-6 is a valid CAS Registry Number.
