156666-23-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156666-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,6,6 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 156666-23:
(8*1)+(7*5)+(6*6)+(5*6)+(4*6)+(3*6)+(2*2)+(1*3)=158
158 % 10 = 8
So 156666-23-8 is a valid CAS Registry Number.

Synthesis and Characterization of a Chiral Dendrimer Derived from Pentaerythritol
Kremers, John A.,Meijer, E. W.
, p. 4262 - 4266 (2007/10/02)
The synthesis and characterization of chiral dendrimer 1 in its racemic form is reported.The chirality of this macromolecule, with a molecular weight of 2831, is based on a pentaeythritol core, acting as a stereocenter with four dendritic substituents of
