Check Digit Verification of cas no
The CAS Registry Mumber 120933-61-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,9,3 and 3 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 120933-61:
(8*1)+(7*2)+(6*0)+(5*9)+(4*3)+(3*3)+(2*6)+(1*1)=101
101 % 10 = 1
So 120933-61-1 is a valid CAS Registry Number.

Synthesis of 2,3-Quinolinedicarboxylic Acid
Maulding, Donald R.
, p. 1777 - 1779 (2007/10/02)
A new procedure for making 2,3-quinolinedicarboxylic acid (6), starting with aniline and maleic anhydride has been developed.Evidence for the formation of 2-anilino-3-formyl-N-phenylmaleimide (7) in the cyclization of 3-phenylimino-4-dimethylaminomethylene-N-phenylsuccinimide (4a) to N-phenylacridinimide (5a) is presented.
