91766-89-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91766-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,6 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 91766-89:
(7*9)+(6*1)+(5*7)+(4*6)+(3*6)+(2*8)+(1*9)=171
171 % 10 = 1
So 91766-89-1 is a valid CAS Registry Number.

Cyclic Siloxanes with Mesogenic Side Groups

Kreuzer, F.-H.,Andrejewski, D.,Haas, W.,Haeberle, N.,Riepl, G.,Spes, P.

, p. 345 - 378 (2007/10/02)

Cyclic liquid crystalline siloxanes (CLCS) are optical uniaxial positive (SA, N) and negative (N*) materials in accordance with calamitic structures.X-Ray measurements indicate, that the distances of SA layers correspond with the length of the monomer unit.In the case of mesogens with high polarity the distance is 1.7 fold the length of the monomer unit.A bundle model is proposed for CLC siloxanes.
