Check Digit Verification of cas no
The CAS Registry Mumber 52364-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,3,6 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 52364-71:
(7*5)+(6*2)+(5*3)+(4*6)+(3*4)+(2*7)+(1*1)=113
113 % 10 = 3
So 52364-71-3 is a valid CAS Registry Number.

CHARACTERIZATION OF THE HEXATIC B AND CRYSTAL B PHASES BY OPTICAL MICROSCOPY.
Goodby,Pindak
, p. 233 - 247 (1981)
Recent investigations concerning the structure of the B phase have unearthed a variety of packing arrangements of the molecular layers for this smectic modification. Two general structures have been discovered; one in which the B phase has three-dimensional crystalline order (crystal B), and one that is characterized by short-range in-plane positional ordering of the constituent molecules, and long-range bond orientational order, both within and between the layers (hexatic B). In this present study n-hexyl 4 prime -n-pentyloxybiphenyl-4-carboxylate (650BC) has been synthesized and its smectic phases characterized. Typically, this ester exhibits an A,B,E phase sequence, with the B phase being of the hexatic type. The synthesis, microscopic textures, and miscibility studies are reported here. The results show that while the two types of B phase appear co-miscible by conventional optical methods, in fact X-ray diffraction studies show that a transition occurs between the two phases in certain binary mixtures. Thus, the hexatic B and crystal B modifications are thermodynamically distinct phases.

A preparative method was developed for the synthesis of liquid crystals of the 4-alkoxy-4'-cyanobiphenyl group.It involves the nitration of 4-cyanobiphenyl to 4-nitro-4'-cyanobiphenyl, reduction of the latter, diazotization of the obtained 4-amino-4'-cyanobiphenyl, and alkylation of the 4-hydroxy-4'-cyanobiphenyl formed during decomposition of the diazonium salt.
