Check Digit Verification of cas no

The CAS Registry Mumber 109735-70-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,7,3 and 5 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 109735-70:
(8*1)+(7*0)+(6*9)+(5*7)+(4*3)+(3*5)+(2*7)+(1*0)=138
138 % 10 = 8
So 109735-70-8 is a valid CAS Registry Number.

On the Aminolysis of Bis-Imidoylchlorides of Oxalic Acid. Part I. Reaction with Aromatic and Aliphatic Amines

Lindauer, Dirk,Beckert, Rainer,Doering, Manfred,Fehling, Peer,Goerls, Helmar

, p. 143 - 152 (2007/10/02)

The reaction between bis-imidoylchlorides 2 derived from oxalic acid several aromatic and aliphatic amines was investigated.While primary aromatic amines need a thermical activation by refluxing, primary aliphatic amines give mainly at room temperature the amidines 3 in moderatly up to good yields.Proceeding from enantiomeric pure amines e.g. (R)- or (S)-1-phenylethylamine the new homochiral axalic amidines 3y and 3z with C2-symmetry were obtained.Several secondary amines react with the bis-imidoylchloride 2a to give via intramolecular cycloacylation derivatives of isatine.The new synthesized amidines 3 perform systems with a strong molecular dynamic like prototropic and E/Z-interconversion.All new compounds described were characterized by elemental analysis and spectroscopic methods.
