[1,2-Ethenediylbis(oxy)]bis[trimethyl-], also known as bis(2-hydroxytrimethyl)methane or bis-GMA, is a chemical compound with the molecular formula C9H20O4. It is a colorless, viscous liquid that is soluble in most organic solvents. [1,2-ethenediylbis(oxy)]bis[trimethyl- is primarily used as a cross-linking agent in the production of unsaturated polyester resins, dental composites, and other polymer materials. It enhances the mechanical properties, chemical resistance, and thermal stability of the final products. Bis-GMA is also known for its potential use in the synthesis of various polymers and as a monomer in the production of polyurethane foams.
The CAS Registry Mumber 6039-89-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,3 and 9 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 6039-89: (6*6)+(5*0)+(4*3)+(3*9)+(2*8)+(1*9)=100 100 % 10 = 0 So 6039-89-0 is a valid CAS Registry Number.
