425613-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 425613-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,5,6,1 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 425613-39:
(8*4)+(7*2)+(6*5)+(5*6)+(4*1)+(3*3)+(2*3)+(1*9)=134
134 % 10 = 4
So 425613-39-4 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.
