86610-21-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 86610-21-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,6,1 and 0 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86610-21:
(7*8)+(6*6)+(5*6)+(4*1)+(3*0)+(2*2)+(1*1)=131
131 % 10 = 1
So 86610-21-1 is a valid CAS Registry Number.

Intramolecular Addition of Enolates to Pyridinium Ions: Formation of Spiro
Weller, Dwight D.,Luellen, Glenn R.,Weller, Doreen L.
, p. 3061 - 3067 (2007/10/02)
Intramolecular addition of ketone and ester enolates to N-alkylpyridinium species produced spiro in 82-93percent yields.When the ketone adducts were treated with hydriodic acid in ethanol at room temperature and the est
