(+/-)-2,2'-bis(hydroxymethylene)-5,5',6,6'-tetramethylbiphenyl is a complex organic compound with the molecular formula C18H22O2. It is a chiral molecule, meaning it has a non-superimposable mirror image, and is represented by the (+/-) notation. (+/-)-2,2'-bis(hydroxymethylene)-5,5',6,6'-tetramethylbiphenyl consists of a biphenyl core, which is a type of aromatic compound with two benzene rings connected by a single bond. The biphenyl core in this molecule is substituted with two hydroxymethylene groups (-CH2OH) at the 2 and 2' positions, and four methyl groups (-CH3) at the 5, 5', 6, and 6' positions. These substitutions result in a highly branched and sterically hindered structure, which can influence its physical and chemical properties, such as solubility, reactivity, and potential applications in various fields, including materials science and pharmaceuticals.
The CAS Registry Mumber 7343-08-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,3,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7343-08: (6*7)+(5*3)+(4*4)+(3*3)+(2*0)+(1*8)=90 90 % 10 = 0 So 7343-08-0 is a valid CAS Registry Number.
