2-((E)-11-Benzenesulfonyl-undec-9-enyloxy)-tetrahydro-pyran is a complex organic compound characterized by a tetrahydro-pyran ring, which is a saturated six-membered cyclic ether. The molecule features a benzenesulfonyl group attached to an undec-9-enyloxy chain, with the double bond in the E configuration, indicating that the substituents are on opposite sides of the double bond. This chemical structure is significant in the field of organic chemistry, potentially serving as an intermediate in the synthesis of more complex molecules or as a component in various chemical reactions. Its unique arrangement of functional groups and stereochemistry make it an interesting subject for study in chemical research and development.

Check Digit Verification of cas no

The CAS Registry Mumber 87242-04-4 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 87242-04:
(7*8)+(6*7)+(5*2)+(4*4)+(3*2)+(2*0)+(1*4)=134
134 % 10 = 4
So 87242-04-4 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
