162281-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 162281-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,2,2,8 and 1 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 162281-31:
(8*1)+(7*6)+(6*2)+(5*2)+(4*8)+(3*1)+(2*3)+(1*1)=114
114 % 10 = 4
So 162281-31-4 is a valid CAS Registry Number.

Synthesis of conjugated-bridged triphenylenes and application in OLEDs

Freudenmann,Behnisch,Hanack

, p. 1618 - 1624 (2001)

Novel conjugated-bridged triphenylene derivatives with electroluminescent properties were synthesized. A six step synthesis yields the cyanomethyltriphenylene derivatives (7a-7d). These were condensed by applying a Knoevenagel reaction with the alkoxy sub

Synthesis of unsymmetrical dibenzoquinoxaline discotic mesogens

Foster, E. Johan,Babuin, Jarret,Nguyen, Natalie,Williams, Vance E.

, p. 2052 - 2053 (2007/10/03)

Unsymmetrical dibenzophenazine discotic mesogens were prepared via the corresponding tetraalkoxybenzfl derivatives. These dibenzophenazines exhibit Colho phases over extremely broad temperature ranges.

Orientational ordering and dynamics in the columnar phase of a discotic liquid crystal studied by deuteron NMR spectroscopy

Shen,Dong,Boden,Bushby,Martin,Wood

, p. 4324 - 4332 (2007/10/03)

The quadropolar splittings and the spin-lattice relaxation data measured in the columnar phase of two differently deuterated HAT6 molecules are interpreted. Modeling the splittings using the AP method allows to obtain the orienting potential needed to describe the reorientational dynamics of molecular disks. It is emphasized that the tumbling motion of a disk can be slightly faster than its spinning motion.
