1334286-77-9 Usage
Description
Hydroxy-PEG2-acid sodium salt is a PEG linker containing a hydroxyl group with a terminal carboxylic acid (as sodium salt form). The free acid form is not stable due to the reaction of OH with PEG-COOH group to form polymer. The sodium salt form is stable for storage and shipping. 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 hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.Check Digit Verification of cas no
The CAS Registry Mumber 1334286-77-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,2,8 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.Calculate Digit Verification of CAS Registry Number 1334286-77:
(9*1)+(8*3)+(7*3)+(6*4)+(5*2)+(4*8)+(3*6)+(2*7)+(1*7)=159
159 % 10 = 9
So 1334286-77-9 is a valid CAS Registry Number.
