The CAS Registry Mumber 216306-45-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,3,0 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 216306-45:
(8*2)+(7*1)+(6*6)+(5*3)+(4*0)+(3*6)+(2*4)+(1*5)=105
105 % 10 = 5
So 216306-45-5 is a valid CAS Registry Number.

Rigid phenylene ethynylene units linked by a V-shaped centre. An approach to biaxial nematogens?

Lehmann, Matthias,Levin, Jeremy

, p. 273/[1315]-281/[1323] (2007/10/03)

Encouraged by theoretical predictions that nematic phases formed from V-shaped compounds could be biaxial, shape-persistent phenylene ethynylene arms linked by 1,3-phenylene, 4,4′-diphenylenemethane and 3,6-fluorenone units have been synthesized. Crystall

2-Bromo-5-iodo-hydroquinone and its symmetrical and unsymmetrical dialkylethers
