80221-13-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80221-13-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,2,2 and 1 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80221-13:
(7*8)+(6*0)+(5*2)+(4*2)+(3*1)+(2*1)+(1*3)=82
82 % 10 = 2
So 80221-13-2 is a valid CAS Registry Number.

, p. 78 - 80 (2011)
Functionalisation of quinoline N-oxide was investigated using phophazene base as a catalyst; alkynylation and heteroarylation at 2-position were successfully achieved via nucleophilic addition-elimination process.
