83405-92-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83405-92-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,0 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83405-92:
(7*8)+(6*3)+(5*4)+(4*0)+(3*5)+(2*9)+(1*2)=129
129 % 10 = 9
So 83405-92-9 is a valid CAS Registry Number.

Ring-alkyl connecting group effect on mesogenic properties of p-carborane derivatives and their hydrocarbon analogues

Jankowiak, Aleksandra,Kaszynski, Piotr,Tilford, William R.,Januszko, Adam,Ohta, Kiminori,Nagamine, Takashi,Endo, Yasuyuki

supporting information; experimental part, (2010/07/18)

The effect of the phenyl-alkyl connecting group on mesogenic properties of several series of isostructural compounds containing p-carborane (A and B), bicyclo[2.2.2]octane (C), and benzene (D) was investigated using thermal and optical methods. Results de

THE EFFECT OF CARBONYL CONTAINING SUBSTITUENTS IN THE TERMINAL CHAINS ON MESOMORPHIC PROPERTIES IN AROMATIC ESTERS AND THIOESTERS, 2. ACYLOXY GROUPS ON THE PHENOLIC END

Neubert, Mary E.,Wildman, Patricia J.,Zawaski, Michael J.,Hanlon, Carol A.,Benyo, Theresa L.,Vries, Adriaan De

, p. 111 - 158 (2007/10/02)

The effect of replacing an alkoxy (Y=OR') with acyloxy (Y=OCOR') group on the phenolic end of the esters: on their mesomorphic properties has been studied.These esters were prepared by esterification of 4-acyloxyphenols with the appropriate acid chloride.The phenols were synthesized by acylation of 4-benzyloxyphenol with either an aliphatic acid or acid chloride followed by catalytic hydrogenolysis of the benzyl group.A comparison of the melting and clearing temperatures of these acyloxy esters with the corresponding known alkoxy ones showed small increases in both these temperatures for the acyloxy esters.The same types of mesophases (N, SA, SC, SB) were observed in both series, but the SB was more favored when Y=OCOR'.The SC phase was found to occur in the acyloxy series at chain lengths beyond which it disappeared in the alkoxy series.Comparisons were also made with the mesomorphic properties previously reported for the correponding alkyl and α-keto esters.Some correlation was observed between increasing dipole moments of these substituents and increasing transition temperatures but not in the types of mesophases observed.Fewer mesophases were found when the alkyl chain was attached to the benzene ring through a carbon atom than through an oxygen atom.
