Check Digit Verification of cas no
The CAS Registry Mumber 113445-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,4,4 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 113445-31:
(8*1)+(7*1)+(6*3)+(5*4)+(4*4)+(3*5)+(2*3)+(1*1)=91
91 % 10 = 1
So 113445-31-1 is a valid CAS Registry Number.

CHEMOSELECTIVE INTRAMOLECULAR NITRONE-OLEFIN CYCLOADDITION : AN EFFICIENT ROUTE TO FUNCTIONALIZED CIS HYDRINDANE SYSTEMS
Stanssens, Dirk,Keukeleire, Denis De,Vandewale, Maurits
, p. 813 - 820 (2007/10/02)
Isoxazolidines 5a-c and 8 were obtained via chemoselective nitrone-olefin cycloaddition in suitably modified 1,4-cyclohexadienes 1a-c; 5a and 5c were transformed to highly functionalized cis-hydrindanes.
