Check Digit Verification of cas no
The CAS Registry Mumber 67471-04-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,7 and 1 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67471-04:
(7*6)+(6*7)+(5*4)+(4*7)+(3*1)+(2*0)+(1*4)=139
139 % 10 = 9
So 67471-04-9 is a valid CAS Registry Number.

HOMOLYTIC AMINATION OF BENZO-1,4-DIOXANE
Zorina, L.N.,Safiev, O.G.,Rakhmankulov, D.L.
, p. 261 - 263 (1989)
When 5,6-benzo-1,4-dioxane was reacted with N,N-dialkylchloramines in the presence of FeSO4 at 10-20 deg C in a solution of acetic and sulfuric acids, 6-(N,N-dialkylamino)benzo-1,4-dioxanes and 6-chloro- and 6,7-dichlorobenzo-1,4-dioxanes were obtained.Under the conditions used in the study mainly chlorination products were synthesized.Reaction of 5,6-benzo-1,4-dioxane with the system (NH3OH)2SO4-TiCl3 resulted in the formation of 6-aminobenzo-1,4-dioxane.
