903896-76-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 903896-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,3,8,9 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 903896-76:
(8*9)+(7*0)+(6*3)+(5*8)+(4*9)+(3*6)+(2*7)+(1*6)=204
204 % 10 = 4
So 903896-76-4 is a valid CAS Registry Number.

Dimesogenic compounds consisting of cholesterol and fluorinated azobenzene moieties: Dependence of liquid crystal properties on spacer length and fluorination of the terminal tail

Lee, Woo-Keun,Kim, Kyu-Nam,Achard, Marie France,Jin, Jung-Il

, p. 2289 - 2297 (2007/10/03)

The liquid crystalline (LC) properties of two series of non-symmetric dimesogenic compounds consisting of cholesterol and ring-fluorinated azobenzene mesogenic moieties interconnected by ω-oxyalkanoyl spacers of varying length are compared; one series (F-AOC-n) has the octyloxy tail attached to the fluorinated azobenzene mesogen unit while the other (F-AOCF-n) has the perfluoroheptylmethyloxy tail. In general, compounds with the fluorinated alkoxy tail exhibited a mesophase over a much wider temperature range than those with the alkoxy tail. On the other hand, the F-AOC-n series exhibited a greater variety of mesophases: TGB (twisted grain boundary), chiral smectic C (SC*), antiphase smectic A (SA), cholesteric (N*) and solid state smectic (SX) phases were observed depending on the length of the central spacer, whereas the F-AOCF-n series favored the formation of only the SA phase with the N* phase completely suppressed. Both series showed an odd-even dependence of the isotropization temperature on the spacer length. The Royal Society of Chemistry 2006.
