733693-34-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 733693-34-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,3,3,6,9 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 733693-34:
(8*7)+(7*3)+(6*3)+(5*6)+(4*9)+(3*3)+(2*3)+(1*4)=180
180 % 10 = 0
So 733693-34-0 is a valid CAS Registry Number.

SYNTHESIS, TAUTOMERIZATION AND ACYLATION OF 1-PHENYLPROPANE-2-IMINES

Zielinski, W.,Mazik, M.

, p. 661 - 668 (2007/10/02)

1-Phenylpropane-2-imines and its derivatives substituted in a benzene ring were synthesized in reaction of proper ketones with ammonia.The keto-enol and imine-enamine tautomerisms in starting compounds and reaction products, respectively, were examined by proton nuclear magnetic resonance spectrometry and chemical methods.The determined constants of tautomeric equilibria were correlated with the Hammett ? constants.Electronic effects occurring in the systems under study were discussed basing on the correlations found.A possible use of 1-phenylpropane-2-imines in synthesis of N-acyl derivatives of 2-phenyl-1-methylvinylamines was examined.
