"4,10,11,11-tetramethyl-8-phenyl-2-oxa-3,8,9-triaza-dispiro[4.0.4.1]undeca-3,9-diene-1,7-dione" is a complex organic compound characterized by its unique molecular structure. It features a spiro framework, which is a type of molecule where two rings are connected by a common central atom. In this case, the central atom is part of a dispiro system, which is a more complex variant of a spiro system involving three rings. The compound also includes a phenyl group, which is a benzene ring with a hydrogen atom replaced by an alkyl group, and an oxa group, which is an oxygen atom bonded to two carbon atoms. The presence of multiple methyl groups and a diene system, which are double bonds between carbon atoms, further contribute to its structural complexity. 4,10,11,11-tetramethyl-8-phenyl-2-oxa-3,8,9-triaza-dispiro[4.0.4.1]undeca-3,9-diene-1,7-dione is likely to be found in specialized chemical research or pharmaceutical applications due to its intricate structure and potential for specific interactions with biological targets.
The CAS Registry Mumber 5684-38-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,6,8 and 4 respectively; the second part has 2 digits, 3 and 8 respectively. Calculate Digit Verification of CAS Registry Number 5684-38: (6*5)+(5*6)+(4*8)+(3*4)+(2*3)+(1*8)=118 118 % 10 = 8 So 5684-38-8 is a valid CAS Registry Number.
