Calculate Digit Verification of CAS Registry Number 26926-78:
(7*2)+(6*6)+(5*9)+(4*2)+(3*6)+(2*7)+(1*8)=143
143 % 10 = 3
So 26926-78-3 is a valid CAS Registry Number.

Synthesis of (Z,E)- and (Z,Z)-α-Farnesenes and -Homofarnesenes

Morgan, E. David,Thompson, Lorna D.

, p. 399 - 404 (2007/10/02)

The ant substance (Z,E)-α-farnesene and its isomer (Z,Z)-α-farnesene have been synthesized in an overall yield of 34percent in six stages from methyl cyclopropyl ketone and 6-methylhept-5-en-2-one via a Wittig condensation.A mixture of the corresponding (Z,E)-α-homofarnesene of ants and its (Z,Z) isomer were prepared in much poorer yield by the same method and incompletely characterized.The isomeric identification of both insect materials were confirmed.
