Benzene, 1,1'-(1,2-difluoro-1,2-ethenediyl)bis[4-methyl-, also known as 4,4'-(1,2-difluoroethene-1,2-diyl)bis(4-methylbenzene), is an organic compound with the molecular formula C16H14F2. It is a derivative of benzene, featuring two methyl groups attached to each benzene ring and a 1,2-difluoroethene bridge connecting the two rings. Benzene, 1,1'-(1,2-difluoro-1,2-ethenediyl)bis[4-methyl- is characterized by its symmetrical structure and the presence of fluorine atoms in the ethene bridge, which can influence its chemical properties, such as reactivity and stability. It is typically synthesized for use in various chemical applications, including the production of polymers and as an intermediate in the synthesis of other organic compounds.
The CAS Registry Mumber 1423-71-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 3 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 1423-71: (6*1)+(5*4)+(4*2)+(3*3)+(2*7)+(1*1)=58 58 % 10 = 8 So 1423-71-8 is a valid CAS Registry Number.
