Check Digit Verification of cas no

The CAS Registry Mumber 1309934-66-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,9,9,3 and 4 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1309934-66:
(9*1)+(8*3)+(7*0)+(6*9)+(5*9)+(4*3)+(3*4)+(2*6)+(1*6)=174
174 % 10 = 4
So 1309934-66-4 is a valid CAS Registry Number.

Oppolzer-type intramolecular Diels-Alder cycloadditions via isomerizations of allenamides

Feltenberger, John B.,Hsung, Richard P.

supporting information; experimental part, p. 3114 - 3117 (2011/08/03)

A new approach to Oppolzer's intramolecular Diels-Alder cycloaddition (IMDA) through γ-isomerization of readily available N-tethered allenamides is described. These IMDA reactions are carried out in tandem with the allenamide isomerization or 1,3-H shift,
