Check Digit Verification of cas no

The CAS Registry Mumber 2026-42-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,2 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2026-42:
(6*2)+(5*0)+(4*2)+(3*6)+(2*4)+(1*2)=48
48 % 10 = 8
So 2026-42-8 is a valid CAS Registry Number.

Synthesis, structures, and optical and electrochemical characteristics of novel crown-containing polythiophene systems

Lukovskaya,Bobylyova,Fedorova,Fedorov,Anisimov,Didane,Brisset,Fages

, p. 967 - 974 (2007)

The synthesis, structures, and optical and electrochemical characteristics of novel crown-containing styryl mono-and polythiophenes were described. The double bonds were constructed by the Horner-Wadsworth-Emmons method. The Suzuki and Stille cross-coupling reactions were used to create polythiophene chains. Optical measurements revealed intense absorption and fluorescence of crown-containing polythiophenes; the band positions and shapes in their absorption and emission spectra depend on the structure of the polythiophene. The electrochemical characteristics of the compounds obtained were measured.

Synthesis and properties of novel t-type nonlinear optical polyurethane containing tricyanovinylthienyl group with enhanced thermal stability of dipole alignment

Cho, You Jin,Kim, Mi Sung,Lee, Ju-Yeon

experimental part, p. 424 - 430 (2011/12/22)

A novel T-type polyurethane 7 containing 1-(2,5-dioxyphenyl)-2-(5-(1,2,2- tricyanovinyl)-2-thienyl)ethenes as NLO chromophores, which constitute part of the polymer backbone, was prepared. Polyurethane 7 is soluble in common organic solvents such as DMF and DMSO. It shows a thermal stability up to 270 °C from TGA thermogram with Tg value obtained from DSC thermogram near 155 °C. The second harmonic generation (SHG) coefficient (d33) of poled polymer film at 1560 nm fundamental wavelength is 3.56 × 10-9 esu. Polymer 7 exhibits a thermal stability even at 5 °C higher than T g, and no significant SHG decay is observed below 160 °C, which is acceptable for nonlinear optical device applications.

Electronic structural dependence of the photophysical properties of fluorescent heteroditopic ligands - Implications in designing molecular fluorescent indicators

Younes, Ali H.,Zhang, Lu,Clark, Ronald J.,Davidson, Michael W.,Zhu, Lei

experimental part, p. 5431 - 5441 (2011/01/12)

Two fluorescent heteroditopic ligands (2a and 2b) for zinc ion were synthesized and studied. The efficiencies of two photophysical processes, intramolecular charge transfer (ICT) and photoinduced electron transfer (PET), determine the magnitudes of emission bathochromic shift and enhancement, respectively, when a heteroditopic ligand forms mono- or dizinc complexes. The electron-rich 2b is characterized by a high degree of ICT in the excited state with little propensity for PET, which is manifested in a large bathochromic shift of emission upon Zn2+ coordination without enhancement in fluorescence quantum yield. The electron-poor 2a displays the opposite photophysical consequence where Zn2+ binding results in greatly enhanced emission without significant spectral shift. The electronic structural effects on the relative efficiencies of ICT and PET in 2a and 2b as well as the impact of Zn2+-coordination are probed using experimental and computational approaches. This study reveals that the delicate balance between various photophysical pathways (e.g. ICT and PET) engineered in a heteroditopic ligand is sensitively dependent on the electronic structure of the ligand, i.e. whether the fluorophore is electron-rich or poor, whether it possesses a donor-acceptor type of structure, and where the metal binding occurs.
