89154-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 89154-51-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,1,5 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89154-51:
(7*8)+(6*9)+(5*1)+(4*5)+(3*4)+(2*5)+(1*1)=158
158 % 10 = 8
So 89154-51-8 is a valid CAS Registry Number.

Investigations on a Cycloheptatriene-Norcaradiene Equilibrium Observable at Room Temperature

Neidlein, Richard,Radke, Christoph Martin

, p. 2626 - 2631 (1983)

Analytical data of the bridged quinone hydrazones 7a, 8a, 7b, 8b, 7c, 8c are discussed.These products exist as tautomeric mixtures of their norcaradiene- and cycloheptatriene forms.The rate constants of these isomerations are so small that the 1H- and 13C-NMR signals of the tautomers are well-resolved.Kinetic and thermodynamic variables were determined by temperture-dependent 1H-NMR, measurements.
