20399-89-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 20399-89-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20399-89:
(7*2)+(6*0)+(5*3)+(4*9)+(3*9)+(2*8)+(1*9)=117
117 % 10 = 7
So 20399-89-7 is a valid CAS Registry Number.

Enamines from Iodine Oxidation of Trialkylamines. 1. Electrophilic Capture by Cationic Heterocyclic Rings

Wadsworth, Donald H.,Detty, Michael R.,Murray, Bruce J.,Weidner, Charles H.,Haley, Neil F.

, p. 2676 - 2681 (2007/10/02)

Simple enamines derived from acetaldehyde, acetone, and propionaldehyde were generated in situ by iodine oxidation of triethylamine, N,N-diisopropylmethylamine, and tri-n-propylamine, respectively.The enamines were captured by a variety of cationic substrates including trityl, indolizinium, dithiolium, pyrylium, thiapyrylium, selenapyrylium, and tellapyrylium cations.The use of a second equivalent of iodine (or excess) oxidized the initial products of enamine capture to various iminium dyes.These dyes were easily hydrolyzed to heterocyclylidene aldehydes and ketones.Cyclic amines such as N-methylpyrrolidine gave enamines derived from ring oxidation. 2-Cyano-N,N-dimethylethylamine generated a cyano-substituted enamine under the reaction conditions.
