Cis-bicyclo[5.4.0]undecane is a cyclic hydrocarbon compound with the molecular formula C11H20. It features a unique bicyclic structure, where two carbon rings are fused together, with one ring containing five carbon atoms and the other containing four. The "cis" descriptor indicates that the two substituents on the bridgehead carbon atoms are on the same side of the molecule. cis-bicyclo<5.4.0>undecane is known for its rigid structure and is often used as a building block in the synthesis of more complex organic molecules, particularly in the pharmaceutical and chemical industries. It is also of interest in materials science due to its potential applications in the creation of novel polymers and other advanced materials.

Check Digit Verification of cas no

The CAS Registry Mumber 1502-19-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,0 and 2 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1502-19:
(6*1)+(5*5)+(4*0)+(3*2)+(2*1)+(1*9)=48
48 % 10 = 8
So 1502-19-8 is a valid CAS Registry Number.

Photochemistry of Trans-Fused Bicyclo 2,4-Dienes. Ground-State Conformational Control in Rigid Systems.

Dauben, William G.,Olsen, Eric G.

, p. 3377 - 3382 (1980)

The photochemistry of a series of simple trans-fused bicyclo 2,4-dienes (n=3, 4, 5) which possess semirigid structures in the ground state has been studied. trans-Bicyclonona-2,4-diene gave rise to cis,cis,cis-cyclonona-1,3,5-triene, the first example of a nonaccordant cyclohexadiene ring opening.The trans-bicyclodeca-2,4-diene at -40 deg C, using 254-nm light, yielded trans,cis,trans-cyclodeca-1,3,5-triene.This triene upon further irradiation yielded endo,endo-tricyclo2,10>dec-8-ene.The triene was extremely thermally labile and was readily converted to cis-bicyclodeca-2,4-diene.At -78 deg C, the photostationary state of trans-bicyclodeca-2,4-diene showed a wavelenght dependency.The photochemistry of trans-bicycloundeca-8,10-diene was analogous to that of the ten-carbon analogue.
