Check Digit Verification of cas no

The CAS Registry Mumber 153561-74-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,5,6 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 153561-74:
(8*1)+(7*5)+(6*3)+(5*5)+(4*6)+(3*1)+(2*7)+(1*4)=131
131 % 10 = 1
So 153561-74-1 is a valid CAS Registry Number.

Selective synthesis of α-substituted oligothiophenes

Bauerle,Wurthner,Gotz,Effenberger

, p. 1099 - 1103 (1993)

An improved synthesis of selectively mono- and dibrominated oligothiophenes using the system N-bromosuccinimide/dimethylformamide is reported together with the preparation of the corresponding α-alkyl and α,α-dialkyl derivatives which represent potent biologically active agents.

End-capping of conjugated thiophene-benzene aromatic systems

Wex, Brigitte,Jradi, Fadi M.,Patra, Digambara,Kaafarani, Bilal R.

, p. 8778 - 8784 (2010)

The synthesis of end-capped thieno[3,2-f:4,5-f′]bis[1]benzothiophene was achieved from thiophene and 2,5-thiophenedicarboxaldehyde. Specifically, hexyl and dodecyl end-capping groups conferred reversible redox behavior as evidenced by cyclic voltammetry with oxidation potentials of 0.73 V versus Fc/Fc+ couple. An extensive spectrophotometric analysis is reported.

Probe of molecular ordering in photoconductive smectic mesophases by transient photocurrent measurement

Funahashi, Masahiro,Hanna, Jun-Ichi

, p. 303 - 310 (2001)

We have studied the carrier transport properties of the two series of smectic mesophases, from SmA to SmE phases, and from SmC to SmG phases in 2-pahenynaphthalene and terthiophene derivatives by time of flight measurements. We examine the experimental data with the hopping transport formalism as a function of the molecular distance with the reference to that from X-ray diffraction. We propose another aspect of the carrier transport characteristics as a probe for elucidating the molecular alignment in the smectic layer.

Synthesis and mesophase behavior of phenylthiophene based amphiphilic molecules

Jing, Shan,Zhang, Ruilin,Dai, Heng,Du, Chao,Cheng, Xiaohong

, p. 577 - 584 (2012/06/04)

Novel amphiphilic molecules consisting of a rigid 2-phenylthiophene core, with a polar flexible tri(oxylethylene) moiety attached to the phenyl ring and one or two alkyl chains attached to the thiophene ring at the other side have been synthesized by using Ni(II) and Pd(0) catalyzed coupling reaction as key steps. The tri(oxylethylene) moieties were terminated with hydroxyl group, sodium carboxylate group and lithium carboxylate group respectively. The thermotropic and solvent induced liquid crystalline behavior of these substances was investigated by polarized optical microscopy, differential scanning calorimetry and X-ray diffraction. Thereby the influence of the terminal groups attached to the tri(oxylethylene) moities as well as the influence of the length and the number of the alkyl chains on the mesophase behavior were investigated. The single alkyl chain Na-carboxylate termianted derivatives show smectic A phases, double alkyl chain Na-carboxylate terminated derivatives show a thermo tropic hexagonal columnar mesophase, while columnar mesophases are found in both single and double alkyl chain Li-carbonate terminated derivatives. The model for molecular organization in the hexagonal columnar mesophase is established.

Bent-core mesogens with thiophene units

Geese, Karina,Prehm, Marko,Tschierske, Carsten

, p. 9658 - 9665 (2011/06/09)

Bent-core mesogens with thiophene and 2,2′-bithiophene units at the periphery of the aromatic core were synthesized and investigated by polarizing microscopy, XRD and electrooptical methods. Resorcinol, 2,7-naphthalenediol and 3,4′-biphenyldiol were used as bent units, phenyl thiophene-2-carboxylates form the rod-like wings and n-alkyl chains as well as olefin- and silylated-terminated alkyl chains were attached as flexible end-groups. A broad variety of different mesophase structures, incorporating ferroelectric and antiferroelectric switching smectic as well as modulated smectic phases, was obtained. Compared with the corresponding benzoates, these thiophene derived compounds form nearly identical LC phase structures, but have significantly reduced transition temperatures, which make them advantageous for applications.
