Check Digit Verification of cas no

The CAS Registry Mumber 450409-51-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,0,4,0 and 9 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 450409-51:
(8*4)+(7*5)+(6*0)+(5*4)+(4*0)+(3*9)+(2*5)+(1*1)=125
125 % 10 = 5
So 450409-51-5 is a valid CAS Registry Number.

Preparation of 7-alkylamino-2-methylquinoline-5,8-diones

Choi, Han Young,Kim, Dong Wook,Chi, Dae Yoon,Yoon, Eun Young,Kim, Dong Jin

, p. 5390 - 5393 (2002)

Several novel 7-alkylamino-2-methylquinoline-5,8-diones (2) were synthesized from 2,5-dimethoxyaniline in five steps via the Skraup reaction followed by demethylations, oxidative bromination, amination, and debromination. We have achieved an unusual hydrobromic acid catalyzed debromination reactions of several 6-bromo-7-alkylamino-2-methylquinoline-5,8-diones, giving 7-alkylamino-2-methylquinoline-5,8-diones in good yields.
