Check Digit Verification of cas no

The CAS Registry Mumber 153749-71-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,4 and 9 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 153749-71:
(8*1)+(7*5)+(6*3)+(5*7)+(4*4)+(3*9)+(2*7)+(1*1)=154
154 % 10 = 4
So 153749-71-4 is a valid CAS Registry Number.

2,4-Dihalogenoquinolines. Synthesis, Orientation Effects and 1H and 13C NMR Spectral Studies

Osborne, Alan G.,Buley, Jill M.,Clarke, Helen,Dakin, Rachel C. H.,Price, Paul I.

, p. 2747 - 2756 (2007/10/02)

Isomer ratios for the syntheses of 2,4-dichloroquinolines from meta-substituted and 3,4-disubstituted anilines are reported, a synthesis of 2,4-dibromoquinoline 1b is also described.The structures of certain bromination products 17 and 1f obtained from 4-hydroxy-2-quinolone have been revised.A thorough study of the 1H and 13C NMR spectra of a series of 2,4-dihalogenoquinolines is presented and the effects of the halogen substituents on JCH couplings are highlighted.
