Azido-PEG3-S-PEG4-t-butyl ester is a PEG linker that features an azide group and a t-butyl protected carboxyl group. This molecule is designed to facilitate Click Chemistry due to the presence of the azide group, while the hydrophilic PEG spacer enhances its solubility in aqueous environments. The t-butyl protected carboxyl group (COOH) serves to prevent self-coupling or polymerization under typical acid/amine or acid/hydroxyl coupling conditions, making it a versatile component in various applications.

Check Digit Verification of cas no
The CAS Registry Mumber 2055041-19-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 2,0,5,5,0,4 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.Calculate Digit Verification of CAS Registry Number 2055041-19:
(9*2)+(8*0)+(7*5)+(6*5)+(5*0)+(4*4)+(3*1)+(2*1)+(1*9)=113
113 % 10 = 3
So 2055041-19-3 is a valid CAS Registry Number.
