125700-69-8 Usage
Uses
O-(3,4-Dihydro-4-oxo-1,2,3-benzotriazin-3-yl)-N,N,N?,N?-tetramethyluronium tetrafluoroborate (2-(3,4-dihydro-4-oxo-1,2,3-benzotriazin-3-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate, TBTU) may be used as coupling reagent in the synthesis of macrocyclic polyamine derivatives with various length of linkers, condensation reagent in the large-scale preparation of the hematoregulatory nonapeptide (Glp-Glu-Asp)2-DAS-(Lys)2 (2,SK&F 107647), coupling reagent for peptide synthesis which best suppresses racemization during fragment condensation.
Check Digit Verification of cas no
The CAS Registry Mumber 125700-69-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,7,0 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 125700-69:
(8*1)+(7*2)+(6*5)+(5*7)+(4*0)+(3*0)+(2*6)+(1*9)=108
108 % 10 = 8
So 125700-69-8 is a valid CAS Registry Number.
