4,4'-Bis-(4-ethoxycarbonyl-phenyliminomethyl)-diphenylsulfon is a complex organic compound with the chemical formula C28H26O8S. It is characterized by a diphenylsulfon core, with two phenyl rings connected through a sulfur atom. Each phenyl ring is further substituted with an ethoxycarbonyl group (-COOCH2CH3) and an iminomethyl group (-CH=N-). The iminomethyl groups are attached to the 4-position of the phenyl rings, and they form a bond with the adjacent carbon atom, creating a conjugated system that influences the compound's electronic properties. 4,4'-Bis-(4-ethoxycarbonyl-phenyliminomethyl)-diphenylsulfon is of interest in the field of organic chemistry, particularly for its potential applications in the synthesis of dyes, pharmaceuticals, and other specialty chemicals due to its unique structure and reactivity.
The CAS Registry Mumber 4091-33-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,9 and 1 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 4091-33: (6*4)+(5*0)+(4*9)+(3*1)+(2*3)+(1*3)=72 72 % 10 = 2 So 4091-33-2 is a valid CAS Registry Number.
