4087-64-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4087-64-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,8 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 4087-64:
(6*4)+(5*0)+(4*8)+(3*7)+(2*6)+(1*4)=93
93 % 10 = 3
So 4087-64-3 is a valid CAS Registry Number.

Reaction of some N-acyl-1-alkylamines with polyphosphoric ester PPE: nuclear magnetic resonance and stereochemistry of reaction products

Alesso, Elba N.,Tombari, Dora G.,Iglesias, Graciela Y. Moltrasio,Aguirre, Jose M.

, p. 2568 - 2574 (2007/10/02)

Phenylindanes were obtained from the reaction of N-acyl-1-arylalkylamines with polyphosphoric ester (PPE). cis-1-Methyl-3-(3,4-dimethoxyphenyl)-5,6-dimethoxyindane was synthesized to determine which stereoisomer was produced by N-formyl and N-acetyl-1-(3,4-dimethoxyphenyl)ethylamine with PPE.Nuclear magnetic resonance specta (1H and 13C) of several mono-, 1,3-di-, and 1,2,3-tri-substituted indanes were fully analyzed to provide information on steric interactions and conformation of the cyclopentene ring.Possible cyclodimerization pathways are proposed.
