Check Digit Verification of cas no

The CAS Registry Mumber 203263-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,2,6 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 203263-28:
(8*2)+(7*0)+(6*3)+(5*2)+(4*6)+(3*3)+(2*2)+(1*8)=89
89 % 10 = 9
So 203263-28-9 is a valid CAS Registry Number.

Synthesis of some novel cyanopyridines and isoxazoles bearing sulphonamide moiety and their antimicrobial activity

Patel, V. B.,Sorathiya, S. D.,Parikh, A. R.

, p. 822 - 825 (2007/10/03)

Substituted 2-propen-1-ones 2a-h, prepared by the reaction of p-(2,5-dichlorobenzenesulphonamido)acetophenone 1 with araldehydes, on condensation with malononitrile in the presence of ammonium accetate yield cyanopyridines 3a-h. Also 2a-h on reaction with hydroxylamine hydrochloride in the presence of sodium acetate in acetic acid afford isoxazoles 4a-h. The structures of 3a-h and 4a-h have been established on the basis of elemental analyses and spectral (IR, 1H NMR and mass) data. The products have been screened for their antimicrobial activity against various strains of bacteria and fungi.
