DBCO-NHS Ester, also known as Dibenzylcyclooctyne NHS Ester, is a popular amine-reactive click chemistry reagent derived from DBCO (Dibenzylcyclooctyne). It is characterized by its ability to modify amine-containing molecules in organic solvents, with limited solubility in aqueous media. DBCO-NHS Ester reacts with primary amines, such as the side chain of lysine residues or aminosilane-coated surfaces, at neutral or slightly basic pH to form covalent bonds. Its low molecular weight adds minimal spacer to modified molecules, making it suitable for various applications in different industries.

Check Digit Verification of cas no

The CAS Registry Mumber 1353016-71-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,0,1 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1353016-71:
(9*1)+(8*3)+(7*5)+(6*3)+(5*0)+(4*1)+(3*6)+(2*7)+(1*1)=123
123 % 10 = 3
So 1353016-71-3 is a valid CAS Registry Number.

Strain-promoted "click" modification of a mesoporous metal-organic framework

Liu, Chong,Li, Tao,Rosi, Nathaniel L.

supporting information, p. 18886 - 18888 (2013/01/15)

Strain-promoted "click" chemistry is used to post-synthetically modify the pore walls of azide-functionalized mesoporous bio-MOF-100 (N 3-bio-MOF-100). The reactions proceed in high yield and produce no byproduct. This new method was used to introduce various functional groups into the MOF mesopores, including succinimidyl ester bioconjugation moieties that allow for straightforward coupling of biomolecules to the pore walls.

Strain-promoted copper-free "click" chemistry for 18F radiolabeling of bombesin

Campbell-Verduyn, Lachlan S.,Mirfeizi, Leila,Schoonen, Anne K.,Dierckx, Rudi A.,Elsinga, Philip H.,Feringa, Ben L.

, p. 11117 - 11120 (2012/02/02)

Click for PET: The GRP-receptor-specific peptide bombesin, which is often used for nuclear imaging of tumors, can be labeled with 18F in a mild and rapid manner by using a copper-free azide-alkyne "click" reaction. A range of azides can be used to provide peptides with different hydrophobicities. The resulting 18F radiopharmaceutical tracers (see scheme) maintain their high affinity for the targeted receptor in vitro in human prostate cancer cells. Copyright
