Check Digit Verification of cas no
The CAS Registry Mumber 333383-82-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,3,3,8 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 333383-82:
(8*3)+(7*3)+(6*3)+(5*3)+(4*8)+(3*3)+(2*8)+(1*2)=137
137 % 10 = 7
So 333383-82-7 is a valid CAS Registry Number.

, p. 105 - 108 (2007/10/03)
A practical route to quinoline from anilines through acid-mediated cyclization of 3-(N-aryl-N-sulfonylamino)propionaldehydes has been developed. Treatment of the cyclization products, dihydroquinoline intermediates with KOH in DMSO leads to substituted quinolines.
