Check Digit Verification of cas no

The CAS Registry Mumber 71458-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,5 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71458-13:
(7*7)+(6*1)+(5*4)+(4*5)+(3*8)+(2*1)+(1*3)=124
124 % 10 = 4
So 71458-13-4 is a valid CAS Registry Number.

SYNTHESIS AND SOME PHYSICAL PROPERTIES OF 1-CYCLOHEXYL-2-(4 double prime -HALOBIPHENYL-4 prime -yl)ETHANES.

Takatsu,Takeuchi,Sato

, p. 345 - 355 (2007/10/02)

A series of 1-(trans-4 prime -n-alkylcyclohexyl)-2-(4 double prime -halobiphenyl-4 prime -yl)ethanes, which show nematic phases, was prepared. Their transition temperatures, enthalpies and entropies were measured. Their bulk viscosities, birefringences and dielectric constants were determined by extrapolation. The bulk viscosity as a function of the third power of the van der Waals radius of the halogeno group, the birefringence as a function of the van der Waals radius of the halogeno group, and the dielectric constants as a function of the dipole moment of the halogeno group are discussed for the 1-(trans-4 prime -n-propylcyclohexyl)-2-(4 double prime -halobiphenyl-4 prime -yl)ethanes.

Some series of trans-1-(4-substituted phenyl)-2(trans-4-n-alkylcyclohexyl) ethylenes, which show nematic phases, were prepared. Their transition temperatures, birefringences and bulk viscosities were measured. Their properties are compared with those of o

1-(TRANS-4 prime -N-ALKYLCYCLOHEXYL)-2-(4 double prime -CYANOPHENYL)ETHANES - A NEW SERIES OF STABLE NEMATOGENS OF POSITIVE DIELECTRIC ANISOTROPY.

Carr,Gray,McDonnell

, p. 13 - 28 (2007/10/02)

The synthesis and some important properties of the 1-(trans-4 prime -n-alkylcyclohexyl)-2-(4 double prime -cyanophenyl)ethanes - where n-alkyl equals C//1 to C//7 - are described.
