Check Digit Verification of cas no

The CAS Registry Mumber 98677-94-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,7 and 7 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 98677-94:
(7*9)+(6*8)+(5*6)+(4*7)+(3*7)+(2*9)+(1*4)=212
212 % 10 = 2
So 98677-94-2 is a valid CAS Registry Number.

Thermodynamics of Vinyl Ethers. 31. Isomer Equilibria in Some Six- and Seven-Membered Cyclic Dienes

Taskinen, Esko,Nummelin, Kari

, p. 4844 - 4847 (1985)

The relative thermodynamic stabilities of 1,3-cyclohexadiene and 1,4-cyclohexadiene, together with a number of their alkoxy and other derivatives and some related seven-membered cyclic dienes, have been determined by chemical equilibration in Me2SO and cyclohexane solution at various temperatures.The values of the thermodynamic parameters ΣG, ΔH, and ΔS for the isomerization processes involved are discussed and show clearly that the apparently conjugated diene system of 1,3-cyclohexadiene is devoid of conjugation, contrary to that of 1,3-cycloheptadiene.
