2,4,5,3'-Tetraacetoxy-6,5'-dimethyl-diphenyl-aether is a complex organic compound characterized by its molecular formula C20H20O8. 2,4,5,3'-Tetraacetoxy-6,5'-dimethyl-diphenyl-aether features a diphenyl ether core, which is a type of aryl ether where two phenyl groups are connected by an oxygen atom. The term "2,4,5,3'-tetraacetoxy" indicates that there are four acetoxy groups attached to the phenyl rings at these specific positions, while "6,5'-dimethyl" signifies the presence of methyl groups at the 6th position of one phenyl ring and the 5' position of the other. The acetoxy groups are esters of acetic acid, which can be hydrolyzed to yield the parent phenol and acetic acid. 2,4,5,3'-Tetraacetoxy-6,5'-dimethyl-diphenyl-aether is likely used in chemical synthesis, particularly in the preparation of intermediates for pharmaceuticals or other organic compounds, due to its reactive functional groups and structural features.
The CAS Registry Mumber 4988-79-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,8 and 8 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4988-79: (6*4)+(5*9)+(4*8)+(3*8)+(2*7)+(1*9)=148 148 % 10 = 8 So 4988-79-8 is a valid CAS Registry Number.
