1.3-Bis-<4-(methyl-phenyl-carbamoyl)-phenyl>-harnstoff, also known as 4,4'--carbanilid, is a complex organic compound with the chemical formula C30H26N4O2. 1.3-Bis-<4-(methyl-phenyl-carbamoyl)-phenyl>-harnstoff, 4,4'--carbanilid is characterized by its symmetrical structure, featuring two identical halves connected by a central urea group. Each half consists of a phenyl ring (a six-carbon ring with alternating single and double bonds), a methyl group (a single carbon atom bonded to three hydrogen atoms), and a carbamoyl group (a carbonyl group double-bonded to nitrogen and single-bonded to another carbon or hydrogen). The compound's name reflects its structure, with "N-Methylcarbanilino" indicating the presence of a methyl group attached to a carbanilino group, which is a derivative of aniline (a compound formed from benzene and ammonia). This chemical is likely to be found in research settings or as an intermediate in the synthesis of more complex molecules, given its intricate structure and the presence of multiple functional groups that can participate in various chemical reactions.
The CAS Registry Mumber 5100-33-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,0 and 0 respectively; the second part has 2 digits, 3 and 3 respectively. Calculate Digit Verification of CAS Registry Number 5100-33: (6*5)+(5*1)+(4*0)+(3*0)+(2*3)+(1*3)=44 44 % 10 = 4 So 5100-33-4 is a valid CAS Registry Number.
