Check Digit Verification of cas no
The CAS Registry Mumber 90094-17-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,9 and 4 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 90094-17:
(7*9)+(6*0)+(5*0)+(4*9)+(3*4)+(2*1)+(1*7)=120
120 % 10 = 0
So 90094-17-0 is a valid CAS Registry Number.

SYNTHESIS OF DERIVATIVES OF BENZOQUINOLINES BY THE CONDENSATION OF SCHIFF BASES WITH KETONES
Letunov, V. I.,Tkhor, T. G.
, p. 149 - 151 (2007/10/02)
Unlike arylidene-1-naphthylamines, which undergo cyclization to 1-azaacenaphthene derivatives in the presence of acid, arylidene-1-naphthylamine-8-sulfonic acid adds acetophenones at the azomethine bond with the formation of arylamino ketones and their cyclization products, i.e., benzoquinoline derivatives.
