1191901-33-3 Usage
Description
TCO-NHS Ester is an popular reagent to label amine-containing compound or biomolecule, TCOI enable fast click chemistry with tetrazine.
Uses
Succinimidyl carbonate/NHS functionalized cyclooctene derivative for incorporation of the cyclooctene moiety into amine containing compounds or biomolecules. Cyclooctenes are useful in strain-promoted copper-free click chemistry cycloaddition reactions with 1,2,4,5-tetrazines. This cyclooctene will react with tetrazine functionalized compounds or biomolecules without the need for a catalyst to result in a stable covalent linkage. The 4+2 inverse electron demand Diels-Alder cycloaddition between trans-cyclooctene and tetrazines is the fastest biologically compatible ligation technology reported and has had many applications in biological labeling and imaging.
Check Digit Verification of cas no
The CAS Registry Mumber 1191901-33-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,9,0 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1191901-33:
(9*1)+(8*1)+(7*9)+(6*1)+(5*9)+(4*0)+(3*1)+(2*3)+(1*3)=143
143 % 10 = 3
So 1191901-33-3 is a valid CAS Registry Number.
