1,3,5,7-Octatetraene is an organic compound with the molecular formula C8H10, consisting of a linear arrangement of eight carbon atoms with alternating double bonds between every other carbon atom. This conjugated diene is known for its unique electronic structure, which results in a delocalized π-electron system across the entire molecule. Due to its highly reactive nature, 1,3,5,7-Octatetraene readily undergoes various chemical reactions, such as Diels-Alder cycloadditions, making it an important compound in organic synthesis and a valuable building block for the creation of more complex molecules. Its properties and reactivity are significantly influenced by the conjugated double bond system, which allows for the efficient transfer of electronic charge throughout the molecule.

Check Digit Verification of cas no

The CAS Registry Mumber 1482-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,8 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1482-91:
(6*1)+(5*4)+(4*8)+(3*2)+(2*9)+(1*1)=83
83 % 10 = 3
So 1482-91-3 is a valid CAS Registry Number.

Electronic Energy Levels in a Homologous Series of Unsubstituted Linear Polyenes

D'Amico, Kevin L.,Manos, Christopher,Christensen, Ronald L.

, p. 1777 - 1782 (1980)

Absorption, emission, and exitation spectra of 1,3,5,7-octatetraene, 1,3,5,7,9-decapentaene, and 1,3,5,7,9,11-dodecahexaene have been obtained in room temperature solutions and 77 K glasses.All spectra exibit the chracteristic gap between the origin of the strongly allowed absorption (1Ag --> 1Bu) and the origin of fluorescence (1Ag* --> 1Ag).Comparison with results previously obtained for methyl-substituted polyenes shows that the 1Bu-1Ag* energy gap is a sensitive function of the degree of substitution.Solvent-effects studies have been used to extrapolate transition energies of the unsubstituted polyenes to gas-phase conditions.For the tetraene, pentaene, and hexaene the 1Bu-1Ag* energy differences are 6380, 7050, and 7420 cm-1, respectively.These results are discussed in terms of current theoretical descriptions of polyene electronic states.
