Check Digit Verification of cas no

The CAS Registry Mumber 58743-81-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,7,4 and 3 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 58743-81:
(7*5)+(6*8)+(5*7)+(4*4)+(3*3)+(2*8)+(1*1)=160
160 % 10 = 0
So 58743-81-0 is a valid CAS Registry Number.

Synthesis method of 4-alkyl biphenylacetylene

-

Paragraph 0045; 0047, (2021/06/13)

The invention discloses a synthesis method of 4-alkyl biphenyl acetylene. The synthesis method comprises the following steps: carrying out catalytic hydrogenation reaction on 4-alkyl diketone to obtain 4-alkyl biphenyl; then reacting the 4-alkyl biphenyl with halogen to obtain 4-halogen-4 '-alkyl biphenyl; and allowing 4-halo-4 '-alkyl biphenyl and an ethynylation reagent to be subjected to a coupling reaction to obtain a compound shown in a formula (IV) under the action of alkali. The method creatively adopts a palladium catalyst and lewis acid combined catalytic system to carry out deoxidation reaction on 4-alkyl diketone, and has good selectivity and high yield; in addition, hydrogen is used as a hydrogen source, a byproduct is only water, and the method is environment-friendly.

Synthesis and mesomorphic properties of laterally fluorinated alkyl 4′′-alkylterphenyl-4-yl carbonate liquid crystals

Choluj, Artur,Kula, Przemyslaw,Dabrowski, Roman,Tykarska, Marzena,Jaroszewicz, Leszek

, p. 891 - 900 (2014/01/23)

Fifteen series of homologues of a variety of mono-, di- and trifluorosubstituted alkyl 4′′-alkylterphenyl-4-yl carbonates have been synthesized and their mesomorphic properties have been determined. From among 95 prepared compounds, 40 pure nematogens have been found, as well as 55 mesogens with orthogonal and tilted smectic phases in broad temperature ranges. The type and combination of the LC phase strongly depend on the position and number of the fluorine atoms. Physical properties and correlations between the molecular core fluorosubstitution, the length of the terminal chains and the type and sequence of the liquid crystalline phases, have been determined. The compounds are useful for the formulation of nematic mixtures as well as ferroelectric ones.

Synthesis of Mesogenic Compounds, Catalyzed by Metal Complexes. I. Monoalkylation and Monoarylation of 1,4-Dibromobenzene in the Synthesis of 4-n-Alkyl- and 4-n-Alkoxy-4'-Cyanobiphenyls Catalyzed by Palladium

Bumagin, N. A.,Luzikova, E. V.,Beletskaya, I. P.

, p. 1480 - 1486 (2007/10/03)

New methods of synthesis of mesomorphic 4-n-alkyl- and 4-n-alkoxy-4'-cyanobiphenyls are developed, based on the palladium catalyzed highly selective reactions of 1,4-dibromobenzene with alkyl and aryl Grignard reagents.
