1334177-79-5 Usage
Description
Mal-amido-PEG6-acid is a PEG linker containing a maleimide group and a terminal carboxylic acid. The hydrophilic PEG spacer increases solubility in aqueous media. 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. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
Check Digit Verification of cas no
The CAS Registry Mumber 1334177-79-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,7 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1334177-79:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*7)+(3*7)+(2*7)+(1*9)=155
155 % 10 = 5
So 1334177-79-5 is a valid CAS Registry Number.
