Check Digit Verification of cas no
The CAS Registry Mumber 72681-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,8 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 72681-40:
(7*7)+(6*2)+(5*6)+(4*8)+(3*1)+(2*4)+(1*0)=134
134 % 10 = 4
So 72681-40-4 is a valid CAS Registry Number.

ORIENTATION EFFECTS IN THE SYNTHESIS OF QUINOLINE DERIVATIVES
Osborne, A. G.
, p. 2831 - 2842 (2007/10/02)
The ratio of isomers obtained in the synthesis of quinoline derivatives commencing from m-toluidine and 3,4-dimethylaniline has been studied.Introduction of additional 2- and/or 3-alkyl substituents into the heterocyclic ring has little effect, whilst introduction of a 4-alkyl substituent, either alone or in combination with 2- and/or 3-alkyl groups, causes the proportion of the 5- or 5,6-isomer to fall to zero.In the Beyer synthesis with butanone, 3-condensation predominates, although 1-condensation does occur to a small extent.The quinoline products have been carefully analysed by GLC, NMR and fractional crystallisation techniques, the value of peri-substituent effects in the interpretation of 1H NMR spectra is propounded.
