Tetraphenylurea is an organic compound with the chemical formula C6H4N2(C6H5)4. It is a white crystalline solid that is formed by the reaction of urea with four equivalents of phenyl isocyanate. tetraphenylurea is characterized by its symmetrical structure, with a central urea molecule connected to four phenyl rings through urethane linkages. Tetraphenylurea is known for its thermal stability and is used in various applications, including as a precursor in the synthesis of other organic compounds and as a stabilizer in some chemical processes. Its unique structure also makes it a subject of interest in chemical research, particularly in the study of molecular conformation and the properties of aromatic compounds.

632-89-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 632-89-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 632-89:
(5*6)+(4*3)+(3*2)+(2*8)+(1*9)=73
73 % 10 = 3
So 632-89-3 is a valid CAS Registry Number.
