Description
Methylamino-PEG4-t-butyl ester is a PEG linker containing a methylamine group and a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The methylamine group is reactive with carboxylic acids, carbonyls (ketone, aldehyde) etc. The t-butyl protected carboxyl group can be deprotected under acidic conditions.Check Digit Verification of cas no
The CAS Registry Mumber 1621616-14-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,2,1,6,1 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 1621616-14:
(9*1)+(8*6)+(7*2)+(6*1)+(5*6)+(4*1)+(3*6)+(2*1)+(1*4)=135
135 % 10 = 5
So 1621616-14-5 is a valid CAS Registry Number.
