902525-96-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 902525-96-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,2,5,2 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 902525-96:
(8*9)+(7*0)+(6*2)+(5*5)+(4*2)+(3*5)+(2*9)+(1*6)=156
156 % 10 = 6
So 902525-96-6 is a valid CAS Registry Number.

New chiral building blocks from acetovanillone using lipase A and B from Candida antarctica

Fuglseth, Erik,Anthonsen, Thorleif,Hoff, Bard Helge

, p. 1290 - 1295 (2006)

Acetovanillone has been used as the starting material for the synthesis of a series of secondary alcohols, which were resolved by lipase catalyzed esterification. 1-(4-Benzyloxy-3-methoxyphenyl)ethanol was efficiently resolved using immobilized lipase B from Candida antarctica (Novozym 435, CAL-B), whereas immobilized lipase A from C. antarctica (Novozym 735, CAL-A) was the lipase of choice for the resolution of the corresponding 2-bromo- and 2-chloro-derivatives. The enantioenriched alcohols are new building blocks for potential use in the synthesis of bioactive compounds.
