1334177-87-5 Usage
Description
Cbz-N-amido-PEG8-acid is a PEG linker containing a CBZ-protected amino group and a terminal carboxylic acid. 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 protected amine can be deprotected by acidic conditions.
Check Digit Verification of cas no
The CAS Registry Mumber 1334177-87-5 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, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1334177-87:
(9*1)+(8*3)+(7*3)+(6*4)+(5*1)+(4*7)+(3*7)+(2*8)+(1*7)=155
155 % 10 = 5
So 1334177-87-5 is a valid CAS Registry Number.
