1807534-77-5 Usage
Description
Fluorescein-PEG3-(N-Boc)-amine is a heterobiofunctional PEG linker containing a fluorescein dye and a Boc-protected amine group, which can be regenerated by mild acidic conditions and then be reactive with cabroxylic acid, activated NHS ester, carbonyl (ketone, aldehyde) etc. Fluorescein is a common fluorescent tracer (494nm/521nm) for staining cells, tissues, biomarkers or nanoparticles and this reagent can be used to tag biomolecules and nanoparticles.
Check Digit Verification of cas no
The CAS Registry Mumber 1807534-77-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,8,0,7,5,3 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1807534-77:
(9*1)+(8*8)+(7*0)+(6*7)+(5*5)+(4*3)+(3*4)+(2*7)+(1*7)=185
185 % 10 = 5
So 1807534-77-5 is a valid CAS Registry Number.
