1032347-93-5 Usage
Description
Thiol-PEG12-acid is a PEG linker containing a thiol group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond.Uses
Thio-PEG12-acid can form conjugates with gold nanoparticles to be used in neuroimaging and drug delivery.Check Digit Verification of cas no
The CAS Registry Mumber 1032347-93-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,3,2,3,4 and 7 respectively; the second part has 2 digits, 9 and 3 respectively.Calculate Digit Verification of CAS Registry Number 1032347-93:
(9*1)+(8*0)+(7*3)+(6*2)+(5*3)+(4*4)+(3*7)+(2*9)+(1*3)=115
115 % 10 = 5
So 1032347-93-5 is a valid CAS Registry Number.
