871805-50-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 871805-50-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,1,8,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 871805-50:
(8*8)+(7*7)+(6*1)+(5*8)+(4*0)+(3*5)+(2*5)+(1*0)=184
184 % 10 = 4
So 871805-50-4 is a valid CAS Registry Number.

Synthesis and gelation properties of a new class of α-amino acid-based sector block dendrons
Chow, Hak-Fun,Zhang, Jie
, p. 11279 - 11290 (2007/10/03)
A new series of α-amino acid-based sector block dendrons containing alanine, phenylalanine, and valine dendritic sectors was prepared by a solution phase peptide coupling methodology. The structures of the dendrons were fully characterized by nuclear magn
