26823-92-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 26823-92-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,2 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 26823-92:
(7*2)+(6*6)+(5*8)+(4*2)+(3*3)+(2*9)+(1*2)=127
127 % 10 = 7
So 26823-92-7 is a valid CAS Registry Number.

REACTION OF 1,5-DIHYDROXYNAPHTHALENE WITH AROMATIC AMINES
E'ktova, L.V.,Fokin, E.P.
, p. 733 - 737 (2007/10/02)
The action of heat on 1,5-dihydroxynaphthalene in naphthalene or p-toluidine, blown with air, at 100 deg C leads to the formation of a mixture of 5-hydroxy-4-arylimino-1-naphthalenone, 5-hydroxy-2-arylamino-4-arylimino-1-naphthalenone, 1,5-diarylamino-4,8
