331251-50-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 331251-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,2,5 and 1 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 331251-50:
(8*3)+(7*3)+(6*1)+(5*2)+(4*5)+(3*1)+(2*5)+(1*0)=94
94 % 10 = 4
So 331251-50-4 is a valid CAS Registry Number.

Highly fructose selective transport promoted by boronic acids based on a pentaerythritol core.

Draffin,Duggan,Duggan

, p. 917 - 920 (2001)

We have designed and synthesized a highly lipophilic boronic acid (11) with a molecular shape that makes it much more effective at carrying sugars through organic membranes than a previously used steroidal boronic acid. The corresponding diboronic acid (1

Highly selective lipophilic diboronic acid that transports fructose as the trisdentate 2,3,6-β-D-fructofuranose ester

Draffin, Scott P.,Duggan, Peter J.,Duggan, Sandhya A. M.,Norrild, Jens Chr.

, p. 9075 - 9082 (2007/10/03)

The transport of fructose and glucose through supported liquid membranes promoted by a tetrahedral shaped lipophilic monoboronic acid and diboronic acid, both based on a pentaerythritol core, has been studied. The diboronic acid gave a high fructose/gluco
