Check Digit Verification of cas no

The CAS Registry Mumber 122603-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,0 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 122603-48:
(8*1)+(7*2)+(6*2)+(5*6)+(4*0)+(3*3)+(2*4)+(1*8)=89
89 % 10 = 9
So 122603-48-9 is a valid CAS Registry Number.

Tandem Addition-Cycloaddition Reaction of Oximes with 2,3-Bis(phenylsulfonyl)-1,3-butadiene as a Method for 4-Piperidone Synthesis

Norman, Bryan H.,Gareau, Yves,Padwa, Albert

, p. 2154 - 2161 (2007/10/02)

The reaction of oximes with 2,3-bis(phenylsulfonyl)-1,3-butadiene affords 7-oxa-1-azanorbornanes in high yield.The formation of the bicyclic isoxazolidine involves conjugate addition of the oxime onto the diene to give a transient nitrone that ten undergo

INTRAMOLECULAR CYCLOADDITION REACTIONS OF OXIMES WITH VINYL SULFONES

Padwa, Albert,Norman, Bryan H.

, p. 2417 - 2420 (2007/10/02)

The reaction of oximes with vinyl sulfones containing a ?-bond produce cycloadducts which are derived from an intramolecular dipolar cycloaddition of a transient nitrone.
