Calculate Digit Verification of CAS Registry Number 80825-39:
(7*8)+(6*0)+(5*8)+(4*2)+(3*5)+(2*3)+(1*9)=134
134 % 10 = 4
So 80825-39-4 is a valid CAS Registry Number.

CHEMISTRY OF ENOL ETHERS. LIII. PROTOTROPIC ISOMERIZATION IN THE SERIES OF CYCLIC 1-ALKOXY-1,4-DIENES

Makin, S. M.,Pomogaev, A. I.,Boiko, T. N.,Nikiforova, A. P.

, p. 2033 - 2036 (2007/10/02)

A series of diethyl acetals of 1-cyclohexene-3-carbaldehydes, the pyrolysis of which leads to the formation of cyclic 1-ethoxy-1,4-dienes, were obtained by the acetalization of 1-cyclohexene-3-carbaldehydes, which were obtained by the condensation of conjugated dienes with α,β-unsaturated aldehydes.The prototropic isomerization of the 1-ethoxy-1,4-dienes to corresponding 1-ethoxy-1,3-dienes under the influence of potassium tert-butoxide in dimethyl sulfoxide solution was investigated.
