Bis--methan, also known as 1,1-bis(2-methoxyethoxy)cyclohexane, is a complex organic compound with the chemical formula C14H26O4. It is a colorless liquid at room temperature and is widely used as a curing agent for epoxy resins in various applications, such as adhesives, coatings, and composite materials. The compound's structure consists of a central methan ring with two cyclohexyloxymethoxy-methoxy groups attached to it, which contribute to its reactivity and compatibility with epoxy resins. Its ability to cross-link with epoxy resins results in improved mechanical properties, thermal stability, and chemical resistance in the final product.
The CAS Registry Mumber 1453-18-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 3 respectively; the second part has 2 digits, 1 and 8 respectively. Calculate Digit Verification of CAS Registry Number 1453-18: (6*1)+(5*4)+(4*5)+(3*3)+(2*1)+(1*8)=65 65 % 10 = 5 So 1453-18-5 is a valid CAS Registry Number.
