90331-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90331-43-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,3,3 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 90331-43:
(7*9)+(6*0)+(5*3)+(4*3)+(3*1)+(2*4)+(1*3)=104
104 % 10 = 4
So 90331-43-4 is a valid CAS Registry Number.

Quinone-Amine Reactions, VII: 5-Amino-2,3,4,6-tetrahydrobenzoquinoxalin-6-one

Kallmayer, Hans-Joerg,Seyfang, Karlheinz

, p. 329 - 335 (2007/10/02)

Aminolysis of 2,3-diphthalimido-1,4-naphthoquinone (15) by ethylenediamine (2) yields the title compound 7 as main product, which is also obtained from 18 and 2.In addition 2,3-diamino-1,4-naphthoquinone (17) and 2-amino-3-phthalimidoethylamino-1,4-naphthoquinone (18) are formed.Attempts to produce 7 from 5-acetylamino-2,3,4,6-tetrahydroquinoxalin-6-one (10) did not succed because in acidic solution 10 is preferentially hydrolyzed to 13 whereas in alkaline solution is dehydrogenated to 12.
