887765-92-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 887765-92-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,7,6 and 5 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 887765-92:
(8*8)+(7*8)+(6*7)+(5*7)+(4*6)+(3*5)+(2*9)+(1*2)=256
256 % 10 = 6
So 887765-92-6 is a valid CAS Registry Number.

Self-assembly of chiral depsipeptide dendrimers

Hager, Kristine,Franz, Alexander,Hirsch, Andreas

, p. 2663 - 2679 (2008/02/03)

The self-assembly of chiral depsipeptide dendrons 4, which contain a cyanuric acid building block at their focal point, with the homotritopic Hamilton receptor 1 is reported. The 1:3 compositions of the resulting chiral supramolecular dendrimers, the association constants Kn, and the cooperativity of binding expressed by Scatchard plots and the Hill coefficients nH was determined by NMR titration experiments. The most pronounced positive cooperativity was found for the complexes 1L3 with L being the second-generation dendrons 4c-e. The least stable complexes are formed with the bulky third-generation dendrons 4f-h. Similar results are obtained by the corresponding complexation of the achiral Frechet-type first- to third-generation dendrons 3 with 1. Chiroptical investigations of 1:3 complexes of 1 and 4 reveal chirality transfer from the dendron to the Hamilton receptor as demonstrated by the appearance of new CD absorption bands at 310 nm.
