1189112-05-7 Usage
Description
PEG17 is a polymer consisiting of repeating ethylene glycol subunits and terminal hydroxyl groups. The ethylene glycol units increase the water solubility of hydrophobic compounds, allowing for them to be more compatible in aqueous settings. The terminal hydroxyl groups can react to further derivatize the compound.
Uses
HO-PEG14-OH acts as a reagent in the synthesis of ‘UA’ Orion substance for treatment and prevention of oncological diseases.
Check Digit Verification of cas no
The CAS Registry Mumber 1189112-05-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,9,1,1 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1189112-05:
(9*1)+(8*1)+(7*8)+(6*9)+(5*1)+(4*1)+(3*2)+(2*0)+(1*5)=147
147 % 10 = 7
So 1189112-05-7 is a valid CAS Registry Number.
