1345337-28-1 Usage
Description
Tos-PEG9-t-butyl ester is a PEG linker containing a t-butyl ester and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The tosyl group is a very good leaving group for nucleophilic substitution reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 1345337-28-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,3,3 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1345337-28:
(9*1)+(8*3)+(7*4)+(6*5)+(5*3)+(4*3)+(3*7)+(2*2)+(1*8)=151
151 % 10 = 1
So 1345337-28-1 is a valid CAS Registry Number.
