1314378-19-2 Usage
Description
Lipoamide-PEG3-Mal contains a lipoic acid group and a terminal maleimide group. Lipoic acid contains two sulfur atoms (at C6 and C8) connected by a disulfide bond and is thus considered to be oxidized although either sulfur atom can exist in higher oxidation states. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. The hydrophilic PEG linker increases the water solubility of the compound.
Check Digit Verification of cas no
The CAS Registry Mumber 1314378-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,4,3,7 and 8 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1314378-19:
(9*1)+(8*3)+(7*1)+(6*4)+(5*3)+(4*7)+(3*8)+(2*1)+(1*9)=142
142 % 10 = 2
So 1314378-19-2 is a valid CAS Registry Number.
