1287777-07-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1287777-07-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,7,7,7 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1287777-07:
(9*1)+(8*2)+(7*8)+(6*7)+(5*7)+(4*7)+(3*7)+(2*0)+(1*7)=214
214 % 10 = 4
So 1287777-07-4 is a valid CAS Registry Number.

Synthesis and characterization of achiral bent-core liquid crystalline molecules containing salicylaldimine-based with a wide temperature range of SmCP phase

Liao, Chien-Tung,Liu, Jung-Yo,Zou, Sing-Fang,Wu, Nien-Chieh,Wu, Zheng-Long,Lee, Jiunn-Yih

, p. 124 - 133 (2011/04/15)

The design and synthesis of a series bent-core materials base on a 3,4'-biphenyldiol central core containing salicylaldimine-based and two terminal tetradecyloxy tails are reported. In addition, the effects of lateral substituents (R = F and Cl) at the biphenyl core into 3'-position are examined. These substituents have a strong influence in reducing the clearing temperatures and increasing temperature range of SmCP phase. Upon cooling process the isotropic liquid, compound SB-Cl exhibits the lowest clearing transition temperature of 180 oC and the widest SmCP phase range of 129 °C. The mesophase behaviour were investigated by polarizing optical microscopy (POM), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and electro-optical (EO) measurements in the mesophase temperature range.
