Uses
Different sources of media describe the Uses of 156311-83-0 differently. You can refer to the following data:
1. (3-Hydroxy-3H-1,2,3-triazolo[4,5-b]pyridinato-O)tri-1-pyrrolidinylphosphonium hexafluorophosphate is used as a coupling reagent in solid phase peptide synthesis. It is preferred over HATU, because it does not side react at the N-terminus of the peptide. Compared to the HOBt derivates, PyAOP (and HOAt in general) are more reactive due to the additional nitrogen.
2. PyAOP is a phosphonium salt used as a coupling reagent in solid-phase peptide synthesis, without undergoing side reactions with the amino terminus. PyAOP is a derivative of HOAt (H805070).
Check Digit Verification of cas no
The CAS Registry Mumber 156311-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,3,1 and 1 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156311-83:
(8*1)+(7*5)+(6*6)+(5*3)+(4*1)+(3*1)+(2*8)+(1*3)=120
120 % 10 = 0
So 156311-83-0 is a valid CAS Registry Number.
