Check Digit Verification of cas no

The CAS Registry Mumber 138272-64-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,2,7 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138272-64:
(8*1)+(7*3)+(6*8)+(5*2)+(4*7)+(3*2)+(2*6)+(1*4)=137
137 % 10 = 7
So 138272-64-7 is a valid CAS Registry Number.

The First Thermodynamic Data on the Complexation of Amino Acids with Cryptand 222 in Methanol at 298.15 K

Namor, Angela F. Danil de,Ritt, Marie Claude,Schwing-Weill, Marie-Jose,Neu, Francoise Arnaud,Lewis, David F. V.

, p. 116 - 117 (1990)

The macrobicyclic ligand cryptand 222 can interact with amino acids in methanol to form stable 1:1 complexes; thermodynamic data for these complexation reactions are first reported and together with computer calculations, these suggest active sites on both guest and receptor molecules.
