92912-56-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 92912-56-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,1 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92912-56:
(7*9)+(6*2)+(5*9)+(4*1)+(3*2)+(2*5)+(1*6)=146
146 % 10 = 6
So 92912-56-6 is a valid CAS Registry Number.

A facile one-carbon homologation of aryl aldehydes to amides.

Shen, Wang,Kunzer, Aaron

, p. 1315 - 1317 (2007/10/03)

The easily accessible 2-aryl-1,1-dibromo-1-alkenes can be converted to amides under unusually mild conditions in good to excellent yields. Both electron-donating and electron-withdrawing substitutions on the aromatic rings are tolerated, and the reaction works well with hindered alkylamines. This simple homologation could find broad applications. [reaction: see text]

Electro-organic Reactions. Part 22. An Entry into the Quinolizidine and Benzoquinolizidine Ring Systems via Anodic Methoxylation

Palasz, Peter D.,Utley, James H. P.,Hardstone, J. David

, p. 281 - 292 (2007/10/02)

Examples of the quinolizidine and benzoquinolizidine ring systems (1,1-bisethoxycarbonyl-4-oxo-quinolizidine, 1,3,4,6,7,11b-hexahydro-2H-benzoquinolizidine, and 1,2-t-butyl-3,4,6,7,11b-hexahydro-2H-benzo-quinolizidine) have been synthesized by routes which involve initial anodic methoxylation of piperidine precursors with subsequent intramolecular Lewis acid-catalysed cyclisation reactions.Reaction conditions for such cyclisations have been explored; success depends on a correct choice of catalyst (usually aluminium chloride) and, critically, on steric factors.The stereochemistry of the cyclic products has been established and the stereochemical course of the reactions is commented upon.
