Check Digit Verification of cas no

The CAS Registry Mumber 1009034-75-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,9,0,3 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1009034-75:
(9*1)+(8*0)+(7*0)+(6*9)+(5*0)+(4*3)+(3*4)+(2*7)+(1*5)=106
106 % 10 = 6
So 1009034-75-6 is a valid CAS Registry Number.

Intermolecular and intramolecular pauson-khand reactions of functionalized Allenes

Gonzalez-Gomez, Alvaro,Anorbe, Loreto,Poblador, Amalia,Dominguez, Gema,Perez-Castells, Javier

supporting information; experimental part, p. 1370 - 1377 (2009/04/11)

Pauson-Khand reactions of functionalized allenes with different alkynes give cyclopentenones with generally high regio-and stereoselectivities. The allenes react through their external double bonds, giving cyclopentenones with exocyclic double bond at their β positions and predominantly with E stereochemistry. Some intramolecular reactions with allenynes connected through aromatic rings are described. These give the corresponding heterocycles with moderate to good yields. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
