233277-26-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 233277-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,3,3,2,7 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 233277-26:
(8*2)+(7*3)+(6*3)+(5*2)+(4*7)+(3*7)+(2*2)+(1*6)=124
124 % 10 = 4
So 233277-26-4 is a valid CAS Registry Number.

Chemoenzymatic synthesis of 2-substituted 2-fluoro-1,3-dioxygenated chiral building blocks

Narisano, Enrica,Riva, Renata

, p. 1223 - 1242 (2007/10/03)

A series of 2-substituted-2-fluoro-1,3-dioxygenated chiral building blocks are synthesized via a chemoenzymatic route using either (i) lipase catalyzed monohydrolysis of suitably functionalized malonic diesters, or (ii) lipase catalyzed monoacetylation of suitably functionalized 1,3-propanediols.
