1137109-21-7 Usage
Description
alpha-MaleiMidopropionyl-oMega-succiniMidyl-6(ethylene glycol), also known as Mal-amido-PEG6-NHS, is a heterobifunctional crosslinker with an ethylene oxide spacer that is used for linking amineto sulfhydryl-containing compounds or biomolecules. It contains a maleimide group that reacts with sulfhydryls and a succinimidyl ester group that reacts with amines. The hydrophilic PEG spacer increases solubility in aqueous media, and the NHS ester can be used to label primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The maleimide group forms a covalent bond with a thiol group, enabling the connection of biomolecules with a thiol.

Check Digit Verification of cas no
The CAS Registry Mumber 1137109-21-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,7,1,0 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1137109-21:
(9*1)+(8*1)+(7*3)+(6*7)+(5*1)+(4*0)+(3*9)+(2*2)+(1*1)=117
117 % 10 = 7
So 1137109-21-7 is a valid CAS Registry Number.
