2,3,4,5-Tetramethyl-styrene is an organic compound with the chemical formula C12H16. It is a derivative of styrene, where four methyl groups (CH3) are attached to the benzene ring at positions 2, 3, 4, and 5. 2,3,4,5-tetramethyl-styrene is a colorless liquid with a strong, pungent odor. It is used as a monomer in the production of specialty polymers and copolymers, which have applications in various industries, including plastics, rubber, and coatings. Due to its unique structure, 2,3,4,5-tetramethyl-styrene offers improved thermal stability, chemical resistance, and mechanical properties compared to traditional styrene-based materials.
The CAS Registry Mumber 3937-22-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,3 and 7 respectively; the second part has 2 digits, 2 and 2 respectively. Calculate Digit Verification of CAS Registry Number 3937-22: (6*3)+(5*9)+(4*3)+(3*7)+(2*2)+(1*2)=102 102 % 10 = 2 So 3937-22-2 is a valid CAS Registry Number.
