1378531-80-6 Usage
Description
DBCO-NHCO-PEG5-NHS ester is a PEG linker containing NHS ester that is able to react specifically and efficiently with primary amines such as the side chain of lysine residues or aminosilane-coated surfaces at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and can also provide a long and flexible connection that minimizes steric hindrance during ligation. DBCO is commonly used for copper-free Click Chemistry reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 1378531-80-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,8,5,3 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1378531-80:
(9*1)+(8*3)+(7*7)+(6*8)+(5*5)+(4*3)+(3*1)+(2*8)+(1*0)=186
186 % 10 = 6
So 1378531-80-6 is a valid CAS Registry Number.
