67225-47-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 67225-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,2 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 67225-47:
(7*6)+(6*7)+(5*2)+(4*2)+(3*5)+(2*4)+(1*7)=132
132 % 10 = 2
So 67225-47-2 is a valid CAS Registry Number.

Diastereodivergent synthesis of trisubstituted alkenes through protodeboronation of allylic boronic esters: Application to the synthesis of the californian red scale beetle pheromone

Hesse, Matthew J.,Butts, Craig P.,Willis, Christine L.,Aggarwal, Varinder K.

supporting information, p. 12444 - 12448 (2013/02/23)

E-allylic boronic esters undergo a highly diastereoselective protodeboronation with TBAF·3 H2O to give Z-trisubstituted alkenes. The selectivity can be switched to give predominantly the E-alkene instead by using KHF2/TsOH (see scheme). The utility of the methodology has been illustrated in a short synthesis of a component of the sex pheromone of the Californian red scale beetle. Copyright

NEW SYNTHESIS OF THE CALIFORNIA RED SCALE SEX PHEROMONE

Becker, D.,Sahali, Y.

, p. 4541 - 4546 (2007/10/02)

The target molecules 1 and 2 were synthesized from a common intermediate 6 prepared from (R)-Limonene.The first enantioselective synthesis of 2 is described.

A NEW SYNTHESIS OF CALIFORNIA RED SCALE PHEROMONE FROM S-(+)-CARVONE

Caine, Drury,Crews, Everett

, p. 5359 - 5362 (2007/10/02)

A Retroaldol-Wittig olefination of the S-(+)-carvone derivative 3 is used as a key step in the synthesis of pheromone 1.
