However, further research is needed to fully understand its properties and potential uses.
Check Digit Verification of cas no
The CAS Registry Mumber 13567-42-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,6 and 7 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13567-42:
(7*1)+(6*3)+(5*5)+(4*6)+(3*7)+(2*4)+(1*2)=105
105 % 10 = 5
So 13567-42-5 is a valid CAS Registry Number.

Bicyclooctenones in Synthesis. A New Synthesis of (+/-)-Cedrene using Sequential Inter- and Intra-molecular Michael Reactions
Horton, Michael,Pattenden, Gerald
, p. 811 - 817 (2007/10/02)
A new synthetic approach to cedrene (1) based on sequential inter- and intra-molecular Michael reactions using the bicyclooctenone (21) as the key intermediate is described.Michael addition of the enolate derived from (21) to 2-nitrobut-2-ene, led to a mixture of diastereoisomers of the nitro ketone (22), which was then converted into the 1,4-dione (23).Treatment of (23) with potassium t-butoxide in t-butyl alcohol resulted in smooth intramolecular Michael reaction leading to a mixture of α- (24a; major) and β-isomers of the tricyclo1,5>undecanedione (24) in a combined yield of 73percent.The undecanedione (24) was then converted into (+/-)-cedrene (1) and the corresponding methyl epimer (31a) via the intermediates (25), (26), (27), and (28).
