Check Digit Verification of cas no

The CAS Registry Mumber 69956-59-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,5 and 6 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 69956-59:
(7*6)+(6*9)+(5*9)+(4*5)+(3*6)+(2*5)+(1*9)=198
198 % 10 = 8
So 69956-59-8 is a valid CAS Registry Number.

Photochemical Cycloadditions of 1,3-Dioxoles to Anisole

Mattay, Jochen,Runsink, Jan,Piccirilli, Joseph A.

, p. 15 - 20 (2007/10/02)

Anisole yields both ortho- and meta-cycloadducts upon irradiation in the presence of 1,3-dioxole and 2,2-dimethyl-1,3-dioxole.The mode and the regio- and stereo-selectivities of these cycloadditions are rationalized on the basis of the exciplex-zwitterion mechanism.

A New Type of Electron Acceptor for Diels-Alder Reactions via Radical Cations

Mattay, Jochen,Gersdorf, Joachim,Mertes, Juergen

, p. 1088 - 1090 (2007/10/02)

Ketone-LiClO4 mixtures have been shown to be effective electron acceptors for catalysing Diels-Alder reactions, which may proceed both via the radical cation of the diene and via the radical cation of the dienophile.
