1334172-70-1 Usage
Description
Lipoamido-PEG8-acid contains a lipoic acid group and a carboxylic acid moiety. 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. 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 hydrophilic PEG linker increases the water solubility of the compound.Check Digit Verification of cas no
The CAS Registry Mumber 1334172-70-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,1,7 and 2 respectively; the second part has 2 digits, 7 and 0 respectively.Calculate Digit Verification of CAS Registry Number 1334172-70:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*7)+(3*2)+(2*7)+(1*0)=131
131 % 10 = 1
So 1334172-70-1 is a valid CAS Registry Number.
