161877-70-9 Usage
General Description
The chemical DABCYL-TYR-VAL-ALA-ASP-ALA-PRO-VAL-EDANS is a peptide sequence consisting of the amino acids tyrosine, valine, alanine, aspartic acid, proline, and valine, labeled with the fluorophores DABCYL and EDANS at the N- and C-termini, respectively. DABCYL is a quencher molecule that can efficiently quench the fluorescence of nearby fluorophores, while EDANS is a fluorophore that emits a strong fluorescence signal when excited. This sequence is often used as a fluorescence resonance energy transfer (FRET) pair, where the fluorescence of EDANS is quenched by the proximity of DABCYL. Such pairings are commonly used in experiments to study the proximity and interactions of molecules in biological systems.
Check Digit Verification of cas no
The CAS Registry Mumber 161877-70-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,1,8,7 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 161877-70:
(8*1)+(7*6)+(6*1)+(5*8)+(4*7)+(3*7)+(2*7)+(1*0)=159
159 % 10 = 9
So 161877-70-9 is a valid CAS Registry Number.
