28401-39-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28401-39-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,0 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 28401-39:
(7*2)+(6*8)+(5*4)+(4*0)+(3*1)+(2*3)+(1*9)=100
100 % 10 = 0
So 28401-39-0 is a valid CAS Registry Number.

ENZYMATIC KINETIC RESOLUTION OF CYANOHYDRIN ACETATES AND ITS APPLICATION TO THE SYNTHESIS OF (S)-(-)-FRONTALIN

Ohta, Hiromichi,Kimura, Yoichi,Sugano, Yasushi,Sugai, Takeshi

, p. 5469 - 5476 (2007/10/02)

Kinetic resolution of racemic 1-cyano-1-methylalkyl and alkenyl acetates has been achieved on incubation with Pichia miso IAM 4682, which hydrolyzed selectively the (R)-enantiomer, leving behind the (S)-enantiomer intact.The chiral 1-cyano-1-methyl-5-hexenyl acetate thus obtained was converted to (S)-frontalin via unsaturated diol.

CONVENIENT SYNTHETIC ROUTE TO (+/-) -FRONTALIN

Kongkathip, Boonsong,Sokkho, Rongsan,Kongkathip, Ngampong

, p. 1849 - 1850 (2007/10/02)

(+/-)-Frontalin was synthesized in a few steps sequence starting from ethyl acetoacetate involving intramolecular cyclization using palladium chloride as catalyst
