128892-29-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128892-29-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,9 and 2 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 128892-29:
(8*1)+(7*2)+(6*8)+(5*8)+(4*9)+(3*2)+(2*2)+(1*9)=165
165 % 10 = 5
So 128892-29-5 is a valid CAS Registry Number.

BroP: A new reagent for coupling N-methylated amino acids
Coste,Dufour,Pantaloni,Castro
, p. 669 - 672 (1990)
BroP (bromo tris(dimethylamino) phosphonium hexafluorophosphate) is a particularly suitable reagent for coupling N-methylated amino acids. It is stable and gives very high yields in short reaction times. Dipeptides are obtained without appreciable epimeri
