107909-53-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 107909-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,9,0 and 9 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 107909-53:
(8*1)+(7*0)+(6*7)+(5*9)+(4*0)+(3*9)+(2*5)+(1*3)=135
135 % 10 = 5
So 107909-53-5 is a valid CAS Registry Number.

Electrochemical Reductive Alkylation of Azomethines with 1-Bromadamantane and 9-Bromo-tetrahydro-exo-dicyclopentadiene

Hess, U.,Lieberenz, C.,Feuerherd, B.

, p. 7 - 20 (2007/10/02)

Electrochemically generated radical anions of Schiffbases 1a-11 react in DMF and in the presence of bridgeheadhalogenides as 1-bromoadamantane and 9-bromo-tetrahydro-exo-dicyclopentadiene to 1--adamantanes and the correspondent 9-tetrahydro-exo-dicyclopentadienes.In the course of SET-mechanism originating bridgehead radicals couple with the azomethine-radicalanions at the position of the highest unpaired electron density, which is predominantly the carbon of the C,N-double bond.Only in cases when this density at the N-atom is relatively high, or steric hindrance impedes C-alkylation, N-hydroalkylated products as N,N-disubstituted 1-aminoadamantanes and 9-amino-tetrahydro-exo-dicyclopentadienes are formed.Product distribution, cyclic-voltammetric results and quantumchemical data are discussed in terms of mechanism.
