29949-92-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 29949-92-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,9,4 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 29949-92:
(7*2)+(6*9)+(5*9)+(4*4)+(3*9)+(2*9)+(1*2)=176
176 % 10 = 6
So 29949-92-6 is a valid CAS Registry Number.

Radical Cations of Bridged Bicycloocta-2,5-dienes - Open-Shell Bis-Homoaromatic Systems

Roth, Heinz D.,Abelt, Christopher J.

, p. 2013 - 2019 (1986)

The radical cations of a series of bridged bicycloocta-2,5-dienes have been generated by photoinduced electron transfer to strong electron acceptors (chloranil, fluoranil) in solution.Chemically induced dynamic nuclear polarization effects observed

Regiochemistry in aryl radical cyclization onto methylenecycloalkanes

Ishibashi,Kobayashi,Nakashima,Tamura

, p. 9022 - 9027 (2007/10/03)

Bu3SnH-mediated aryl radical cyclization onto methylenecycloalkanes having a phenylthio, an ester, or a nitrile group at the terminus of the alkenic bond provides exclusively exo cyclization products. The results are in sharp contrast to those reported for nonsubstituted methylenecycloalkanes, which give exclusively endo cyclization products. Formation of endo cyclization products has been suggested to be a result of a consecutive 5-exo cyclization of an aryl radical and neophyl rearrangement. The exo-selective aryl radical cyclization offers a new method for synthesizing fused aromatic compounds containing a benzylic quaternary carbon atom.
