Check Digit Verification of cas no
The CAS Registry Mumber 78523-39-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,5,2 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78523-39:
(7*7)+(6*8)+(5*5)+(4*2)+(3*3)+(2*3)+(1*9)=154
154 % 10 = 4
So 78523-39-4 is a valid CAS Registry Number.

Uncatalyzed Sigmatropic 1,5-Shift of Acyl Groups in the Thermolysis of 5-Acyl-5-methyl-1,3-cyclohexadienes
Schiess, Peter,Dinkel, Rolf,Fuenfschilling, Peter
, p. 787 - 800 (2007/10/02)
Four different 5-acyl-5-methyl-1,3-cyclohexadienes 1a-d (R=COOCH3, COCH3, COC6H5, CHO) have been shown to yield mixtures of 1,3-disubstituted cyclohexadienes 2-7 and 1,3-disubstituted aromatic product 8 upon thermolysis at 150-300 deg C in solution and at 350-500 deg C in the gas phase in a flow system.Two reaction pathways are considered for the rearrangement of the C-Skeleton.For the ester 1a 13C-isotopic substitution shows that products arise to 75-86percent through a 1,5-sigmatropic shift of the methoxycarbonyl group and to 14-25percent through a sequence of reaction steps involving a 1,7-H-shift reaction in an acyclic intermediate.For the more reactive compounds 1b-d isomerization is assumed to follow the 1,5-sigmatropic pathway exclusively.A kinetic study yields the following sequence for the migration tendency of acyl groups toward sigmatropic 1,5-shift: COOCH3 COCH3 COC6H5 CHO.
