2,8-dimethyl-1,7-diphenyl-1,7-diaza-spiro[5.5]undecane is a complex organic compound with a unique molecular structure. It is characterized by a spiro[5.5]undecane backbone, which features a seven-membered ring fused to a five-membered ring. The molecule contains two methyl groups at the 2 and 8 positions, and two phenyl groups attached to the 1 and 7 positions. The presence of the diaza group indicates that there are two nitrogen atoms in the molecule, contributing to its overall structure. 2,8-dimethyl-1,7-diphenyl-1,7-diaza-spiro[5.5]undecane is of interest in the field of organic chemistry, particularly in the synthesis of complex molecules and the study of their properties. Its specific applications may vary, but it could potentially be used in the development of pharmaceuticals, materials science, or as a precursor in the synthesis of other compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 5546-84-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,5,4 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 5546-84:
(6*5)+(5*5)+(4*4)+(3*6)+(2*8)+(1*4)=109
109 % 10 = 9
So 5546-84-9 is a valid CAS Registry Number.

1,7-Diazaspiro[5.5]undecane - A neglected heterocycle

Cordes, Jens,Murray, Philip R. D.,White, Andrew J. P.,Barrett, Anthony G. M.

, p. 4992 - 4995 (2013)

A convenient and simple three step synthesis of 1,7-diazaspiro[5.5]undecane via Claisen condensation and acid catalyzed decarboxylation and spirocyclization of N-Boc-δ-valerolactam is described. Reactions of this spiroaminal with electrophiles including alkyl halides, alkane dihalides, acid chlorides, and sulfonyl chlorides gave either spirocyclic adducts or tetrahydropyridine derivatives. Additionally, the parent heterocycle is a novel bidentate ligand and formed complexes with ruthenium(II) and copper(II).
