Check Digit Verification of cas no

The CAS Registry Mumber 109243-48-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,4 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 109243-48:
(8*1)+(7*0)+(6*9)+(5*2)+(4*4)+(3*3)+(2*4)+(1*8)=113
113 % 10 = 3
So 109243-48-3 is a valid CAS Registry Number.

Intramolecular Nitrone-Quinone Cycloaddition. Formation of Isomeric Isoxazolidines by Kinetic and Thermodynamic Control

Schultz, Arthur G.,McMahon, Wayne G.,Kullnig, Rudolph K.

, p. 3905 - 3909 (1987)

Cyclization of nitrone 5a occurs at 25 deg C to give isoxazolidine 6a; 6a is unstable at higher reaction temperatures and rearranges to isoxazolidine 7a presumably via a 1,3-dipolar cycloreversion to regenerate 5a.Structural assignments for 6a and 7a were
