6259-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 6259-18-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,5 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 6259-18:
(6*6)+(5*2)+(4*5)+(3*9)+(2*1)+(1*8)=103
103 % 10 = 3
So 6259-18-3 is a valid CAS Registry Number.

Arylamination of Halogenoazabenzanthrones
Nabar, U. T.,Kanetkar, V. R.,Sunthankar, S. V.
, p. 812 - 814 (2007/10/02)
6-Halogeno-3-aza- or 1,3-diaza-benzanthrone derivatives (I) react with arylamines in the presence of anhyd.AlCl3 to give 6-arylamino-compounds (II) in high yields.The arylamination reaction is very much similar to that of 1-amino-4-chloroanthraquinone In
