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
