918150-44-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 918150-44-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,1,5 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 918150-44:
(8*9)+(7*1)+(6*8)+(5*1)+(4*5)+(3*0)+(2*4)+(1*4)=164
164 % 10 = 4
So 918150-44-4 is a valid CAS Registry Number.

Azotolane liquid-crystalline polymers: Huge change in birefringence by photoinduced alignment change

Okano, Kunihiko,Tsutsumi, Osamu,Shishido, Atsushi,Ikeda, Tomiki

, p. 15368 - 15369 (2006)

Novel liquid-crystalline polymers (LCPs) containing a long azotolane moiety were synthesized, and the relationship between the chemical structures and the photoresponsive behavior was investigated. All homogeneously aligned LCP films exhibited extremely high values of birefringence (Δn) in the wide wavelength range. Specifically, the azotolane LCP with two azobenzene units showed the most efficient change in the alignment of the azotolane moiety with a huge change in Δn (≥0.65). This means that the high value of Δn in the homogeneously aligned state can be converted to the change in Δn effectively. Copyright
