Check Digit Verification of cas no
The CAS Registry Mumber 4487-51-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,8 and 7 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 4487-51:
(6*4)+(5*4)+(4*8)+(3*7)+(2*5)+(1*1)=108
108 % 10 = 8
So 4487-51-8 is a valid CAS Registry Number.

Mixing with equimolar solutions of pyridine N-oxide or its homologs and SbCl5 in CCl4 deposited 1:1 complexes as colorless crystals in high yield.On thermolysis, these complexes underwent intramolecular oxygen transfer to give selectively the corresponding 2-pyridone derivatives.N,N-Dimethylaniline N-oxide and SbCl5 also gave a crystalline 1:1 complex which on termolysis yield o-dimethylaminophenol in good yield.
