Check Digit Verification of cas no

The CAS Registry Mumber 1023967-90-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,9,6 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1023967-90:
(9*1)+(8*0)+(7*2)+(6*3)+(5*9)+(4*6)+(3*7)+(2*9)+(1*0)=149
149 % 10 = 9
So 1023967-90-9 is a valid CAS Registry Number.

SYNTHESIS AND SOME PHYSICAL PROPERTIES OF 1-CYCLOHEXYL-2-(4 double prime -HALOBIPHENYL-4 prime -yl)ETHANES.

Takatsu,Takeuchi,Sato

, p. 345 - 355 (1983)

A series of 1-(trans-4 prime -n-alkylcyclohexyl)-2-(4 double prime -halobiphenyl-4 prime -yl)ethanes, which show nematic phases, was prepared. Their transition temperatures, enthalpies and entropies were measured. Their bulk viscosities, birefringences and dielectric constants were determined by extrapolation. The bulk viscosity as a function of the third power of the van der Waals radius of the halogeno group, the birefringence as a function of the van der Waals radius of the halogeno group, and the dielectric constants as a function of the dipole moment of the halogeno group are discussed for the 1-(trans-4 prime -n-propylcyclohexyl)-2-(4 double prime -halobiphenyl-4 prime -yl)ethanes.
