Check Digit Verification of cas no

The CAS Registry Mumber 122855-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,8,5 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 122855-45:
(8*1)+(7*2)+(6*2)+(5*8)+(4*5)+(3*5)+(2*4)+(1*5)=122
122 % 10 = 2
So 122855-45-2 is a valid CAS Registry Number.

Intramolecular Host-Guest Complexes Of D- And L-Mono-6-Phenylalanyl-Amino-6-Deoxy Cyclomalto-Heptaoses.

Parrot-Lopez, Helene,Galons, Herve,Coleman, Anthony W.,Djedaini, Florence,Keller, Nelly,Perly, Bruno

, p. 367 - 370 (1990)

Coupling of L- and D-phenylalanine to mono 6-amino-β-cyclodextrin leads to the formation of diastereoisomeric intramolecular inclusion compounds.The proton NMR spectra of the two products show clear chiral discrimination between the two molecules with regard to the interaction of the aromatic moieties with the cyclodextrin cavity.
