Check Digit Verification of cas no

The CAS Registry Mumber 60600-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,0,6,0 and 0 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 60600-49:
(7*6)+(6*0)+(5*6)+(4*0)+(3*0)+(2*4)+(1*9)=89
89 % 10 = 9
So 60600-49-9 is a valid CAS Registry Number.

Facile one-pot syntheses of amidines and enamines from oximes via Beckmann rearrangement using trifluoromethanesulfonic anhydride

Takuwa, Tomofumi,Minowa, Tomofumi,Onishi, Jim Yoshitaka,Mukaiyama, Teruaki

, p. 1717 - 1725 (2007/10/03)

Iminocarbocation intermediates were in situ-generated by treating various oximes with trifluoromethanesulfonic anhydride (Tf2O) in the presence of triethylamine in toluene and nucleophilic trapping with amines or sodium enolates under mild conditions afforded the corresponding amidines and enamines. Some of the thus-obtained enamines were converted to 2-substituted 4-oxo-3-quinolinecarboxylic acid derivatives by subsequent intramolecular Friedel-Crafts acylation.
