86421-21-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 86421-21-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,4,2 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 86421-21:
(7*8)+(6*6)+(5*4)+(4*2)+(3*1)+(2*2)+(1*1)=128
128 % 10 = 8
So 86421-21-8 is a valid CAS Registry Number.

Versatile enantioselective synthesis of four diastereomers of serricornin, a sex pheromone of the cigarette beetle, using the SAMP/RAMP-hydrazone method

Job, Andreas,Nagelsdiek, Rene,Enders, Dieter

, p. 524 - 538 (2000)

Serricornin is a female-produced sex pheromone of the cigarette beetle (Lasioderma serricorne), which is a pest of dried foodstuffs and tobacco. We report a versatile and short synthesis of all possible 6,7-syn-isomers of serricornin, including the natura

Synthesis of (4R,6S,7R)-7-hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5-dimethyl-2-octanone, the pheromone components of the bostrychid beetle, Dinoderus bifoveolatus

Masuda, Yui,Fujita, Ken,Mori, Kenji

, p. 1744 - 1750 (2007/10/03)

(4R,6S,7R)-7-Hydroxy-4,6-dimethyl-3-nonanone and (3R,5S,6R)-6-hydroxy-3,5- dimethyl-2-octanone, the pheromone components of the bostrychid beetle, Dinoderus bifoveolatus, as well as their (4R,6S,7S)-and (3R,5S,6S)-isomers were synthesized from (2R,4S,5R)- and (2R,4S,5S)2,4-dimethyl-5-heptanolide, respectively.

Facile synthesis of (-)-serricornin by means of palladium-catalyzed hydrogenolysis of alkenyloxiranes

Shimizu,Hayashi,Ide,Oshima

, p. 2991 - 2998 (2007/10/02)

Chiral synthesis of (-)-serricornin by using palladium-catalyzed stereoselective hydrogenolysis of the alkenyloxirane to the homoallylic alcohol with formic acid as a key step was carried out.
