Check Digit Verification of cas no

The CAS Registry Mumber 1026888-20-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,8,8 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1026888-20:
(9*1)+(8*0)+(7*2)+(6*6)+(5*8)+(4*8)+(3*8)+(2*2)+(1*0)=159
159 % 10 = 9
So 1026888-20-9 is a valid CAS Registry Number.

Asymmetric synthesis of unnatural (Z,Z,E)-octadecatrienoid and eicosatrienoid by lipoxygenase-catalyzed oxygenation

Nanda,Yadav

, p. 1799 - 1806 (2007/10/03)

The asymmetric synthesis of unnatural 13-hydroxy-(6Z,9Z,11E,13S)-octadecatrienoid and 15-hydroxy-(8Z,11Z,13E,15S)-eicosatrienoid is described using a biomimetic oxidation route. The main highlights of this synthesis are the asymmetric hydroxylation of the substrate with soybean lipoxygenase and cis selective Wittig olefination.
