114396-98-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 114396-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,3,9 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 114396-98:
(8*1)+(7*1)+(6*4)+(5*3)+(4*9)+(3*6)+(2*9)+(1*8)=134
134 % 10 = 4
So 114396-98-4 is a valid CAS Registry Number.

Competitive -Cycloaddition versus -Hydrogen Sigmatropy in a Cycloheptatriene. An Efficient Route to 3-Azatricyclo4,10>undeca-5,8-diene

Krow, Grant R.,Cannon, Kevin C.,Carey, James T.,Ma, Hong,Raghavachari, Ramesh,Szczepanski, Steven V.

, p. 2665 - 2668 (2007/10/02)

Thermal rearrangements of N-acyl-7-aminocyclohepta-1,3,5-trienes 7b-e in octane or xylene provide -cycloaddition products 8b-e and -hydrogen sigmatropic rearrangement products 9b-e.The relative rate of formation for 8e/9e is 1.5 in refluxing octane.At a higher reaction temperature in xylene and longer reaction times, 7b afforded a second hydrogen-shift product 10b.No thermal -carbon shift products were observed from N-allyl cycloheptatrienes 9b-e or 10b in octane or xylene.The thermal behavior of 7b-e can be contrasted with that of O-allyl cyclohepta-1,3,5-triene 1.
