Check Digit Verification of cas no

The CAS Registry Mumber 1182846-71-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,2,8,4 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1182846-71:
(9*1)+(8*1)+(7*8)+(6*2)+(5*8)+(4*4)+(3*6)+(2*7)+(1*1)=174
174 % 10 = 4
So 1182846-71-4 is a valid CAS Registry Number.

7-Chloroquinoline: a versatile intermediate for the synthesis of 7-substituted quinolines

Hirner, Joshua J.,Zacuto, Michael J.

, p. 4989 - 4993 (2009)

A practical synthesis of 7-mono-substituted quinolines has been achieved. Selective reduction of the inexpensive commercial reagent 4,7-dichloroquinoline affords 7-chloroquinoline, which has been converted into more complex 7-mono-substituted quinolines through a series of Pd-catalyzed cross coupling reactions. These studies include the first examples of Suzuki reactions for the preparation of 7-mono-substituted quinolines as well as the first application of the Sonagashira reaction for the synthesis of 7-substituted quinolines. This strategy has been extended to the preparation of 2,7-di-substituted quinolines.
