Check Digit Verification of cas no
The CAS Registry Mumber 82-27-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 2 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 82-27:
(4*8)+(3*2)+(2*2)+(1*7)=49
49 % 10 = 9
So 82-27-9 is a valid CAS Registry Number.

PHOTOCHEMICAL REACTION OF 9,10-ANTHRAQUINONE AND ITS DERIVATIVES WITH PYRIDINE
Loskutov, V.A.,Lukonina, S.M.,Konstantinova, A.V.,Fokin, E.P.
, p. 500 - 504 (2007/10/02)
The previously unknown photochemical reaction of 9,10-anthraquinone with pyridine in an atmosphere of argon takes place with formation of 2-(1,2-dihydropyridino)- or 2-(1,4-dihydropyridino)-9,10-anthraquinone, which is converted by the action of alkali into 2-aminoanthraquinone.In the presence of atmospheric oxygen the reaction product after treatment whith alkali is 1-aminoanthraquinone in addition to 2-aminoanthraquinone.The 1- and 2-methoxyanthraquinones and chloroanthraquinones react with pyridine in the light and form, after treatment with alkali, substituted aminoanthraquinones.
