125263-30-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125263-30-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,2,6 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 125263-30:
(8*1)+(7*2)+(6*5)+(5*2)+(4*6)+(3*3)+(2*3)+(1*0)=101
101 % 10 = 1
So 125263-30-1 is a valid CAS Registry Number.

Synthesis and crystal structure of cis-1-benzylidene-1,2,3,4-tetrahydronaphthalene, containing an unexpected conformation of the cyclohexylidene ring

Bukowska-Strzyzewska, M.,Skoweranda, J.,Maniukiewicz, W.,Strzyzewski, W.

, p. 713 - 720 (1988)

Two isomers of 1-benzylidene-1,2,3,4-tetrahydronaphthalene have been synthesized by the Wittig reaction, and the crystal structure of the cis-isomer has been solved .The compound C17H16 crystallizes in the monoclinic space group P21/n with a = 9.796(2), b = 5.490(5), c = 23.215(3) Angstroem, β = 95.11(2) deg, and Z = 4.The structure was determined by direct methods, and refined by full-matrix least squares to R = 0.047 for 1104 reflections.The cyclohexylidene ring has the unusual envelope Cs2,10 conformation.

The photochemical rearrangement of 1,2-dihydronaphthalenes into 1,4-dihydronaphthalenes induced by amines

Cuppen, Th. J. H. M.,Berendsen, N.,Laarhoven, W. H.

, p. 168 - 171 (2007/10/02)

The synthetic usefulness of the deprotonation/protonation reaction of excited 1,2-dihydronaphthalenes into 1,4-dihydronaphthalenes induced by amines has been investigated using 13 different substituted 1,2-dihydronaphthalenes and related compounds.The yield of the rearrangement ranges from 5 to 96percent.The formation of side-products depends on the position of protons in the substrate, which can be abstracted by the amine, and on competitive photoreactions.
