Check Digit Verification of cas no

The CAS Registry Mumber 72390-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,3,9 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72390-31:
(7*7)+(6*2)+(5*3)+(4*9)+(3*0)+(2*3)+(1*1)=119
119 % 10 = 9
So 72390-31-9 is a valid CAS Registry Number.

Asymmetric Induction in Liquid Crystals: Optically Active trans-Cyclooctene from Hofmann Elimination in New Cholesteric Mesophases

Seuron, Patrick,Solladie, Guy

, p. 715 - 719 (2007/10/02)

Optically active trans-cyclooctene was obtained by Hofmann elimination of trimethylcyclooctyl ammonium hydroxide in new cholesteric liquid crystals.The extent of asymmetric induction rose 7 percent.Enantiomeric equilibration of racemic trans-cyclooctene in cholesteric medium, at 180 deg C, leads to a 2 percent enantiomeric excess.These asymmetric induction results are interpreted in terms of solute-solvent interactions enhanced by the local ordering of the mesophase.
