Check Digit Verification of cas no

The CAS Registry Mumber 77252-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,2,5 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 77252-65:
(7*7)+(6*7)+(5*2)+(4*5)+(3*2)+(2*6)+(1*5)=144
144 % 10 = 4
So 77252-65-4 is a valid CAS Registry Number.

A Carbon-13 Nmr Assignment Study of 3,5-Diarylisoxazoles

Baumstark, Alfons L.,Chrisope, Douglas R.,Keel, Rebecca A.,Boykin, David W.

, p. 1719 - 1721 (2007/10/02)

The assignment of the carbon-13 nmr resonances of 3-(aryl)-5-phenylisoxazoles (I) and 3-phenyl-5-(aryl)isoxazoles (II) in dimethylsulfoxide-d6 has been made.The assignments were made by using model compounds, chemical shift arguments, coupling with fluorine substituents, and shifts resulting from quaternization of the isoxazole ring.A carbon-13 nmr method for distinguishing between I and II which can be produced simulaneously by certain synthetic methods is presented.
