Check Digit Verification of cas no

The CAS Registry Mumber 93866-23-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,8,6 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 93866-23:
(7*9)+(6*3)+(5*8)+(4*6)+(3*6)+(2*2)+(1*3)=170
170 % 10 = 0
So 93866-23-0 is a valid CAS Registry Number.

Asymmetrically substituted distyrylbenzenes and their polar crystal structures

Collas, Alain,Borger, Roeland De,Amanova, Tatyana,Vande Velde, Christophe M. L.,Baeke, Jan K.,Dommisse, Roger,Alsenoy, Christian Van,Blockhuys, Frank

experimental part, p. 649 - 662 (2011/06/20)

The synthesis of twelve asymmetric donor-acceptor distyrylbenzene derivatives with either one nitrile group or one, two or three nitro groups as electron acceptors, and one, two or three methoxy groups as electron donors is reported. Peak potentials obtained from cyclic voltammetry were combined with experimental UV/Vis data and molecular dipole moments obtained from quantum chemical calculations, yielding insight into the influence of the positions of the substituents on the electronic structure and charge distribution of this as yet unexplored class of organic semiconductors. The supramolecular structures of five of these compounds have been studied using single-crystal X-ray diffraction to monitor the influence of the positions of donor and acceptor groups on the organisation of the molecules in the solid state, and three crystal structures have been identified in which the molecular dipoles do not organize themselves in a centrosymmetric lattice. Analysis of the dipoles in the unit cell yields further insight into the possible non-linear optical properties of these three polar structures.
