1. 5(6)-Carboxyfluorescein N-hydroxysuccinimide ester (5(6)-FAM SE, FLUOS) may be used to prepare fluorescent derivatives of proteins such as tubulin and for the preparation of a phenytoin tracer for the determination of this and other drugs in serum and plasma by fluorescence polarization immunoassay (FPIA) and laser-induced fluorescence detection.
2. 5(6)-Carboxyfluorescein N-succinimidyl ester is an amine-reactive green fluorescent dye widely used for labeling proteins or other biomolecules that contain a primary or secondary aliphatic amine.
Check Digit Verification of cas no
The CAS Registry Mumber 117548-22-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,5,4 and 8 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117548-22:
(8*1)+(7*1)+(6*7)+(5*5)+(4*4)+(3*8)+(2*2)+(1*2)=128
128 % 10 = 8
So 117548-22-8 is a valid CAS Registry Number.
