2-((Z)-11-Benzenesulfonyl-undec-9-enyloxy)-tetrahydro-pyran is a complex organic compound with the molecular formula C21H28O5S. It is characterized by a tetrahydro-pyran ring, which is a saturated six-membered cyclic ether, and a Z-configured 11-benzenesulfonyl-undec-9-enyloxy side chain. The Z-configuration indicates that the double bond in the undec-9-enyloxy moiety has a cis arrangement. 2-((Z)-11-Benzenesulfonyl-undec-9-enyloxy)-tetrahydro-pyran is likely to be found in the context of pharmaceuticals or chemical research due to its structural complexity and the presence of a benzenesulfonyl group, which can be a key functional group in various chemical reactions and biological activities.

Check Digit Verification of cas no

The CAS Registry Mumber 87242-07-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,2,4 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 87242-07:
(7*8)+(6*7)+(5*2)+(4*4)+(3*2)+(2*0)+(1*7)=137
137 % 10 = 7
So 87242-07-7 is a valid CAS Registry Number.

Stereoselective Syntheses of E- and Z-9,11-Dodecadien-1-yl Acetates: The Major Sex Pheromones of the Red Bollworm Moth

Ochiai, Masahito,Ukita, Tatsuzo,Fujita, Eiichi

, p. 1641 - 1645 (2007/10/02)

The sex pheromones 1 and 2 of the red bollworm moth were synthesized in a highly stereoselective manner.The key step of their syntheses was the olefination reaction of E- and Z-allyl phenyl sulfones 8 and 12, affording the corresponding dienes 9 and 15, respectively.Keywords - E-9,11-dodecadien-1-yl acetate; Z-9,11-dodecadien-1-yl acetate; sex pheromone; red bollworm moth; allyl sulfone; tri-n-butylstannylmethyl iodide
