278610-81-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 278610-81-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,8,6,1 and 0 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 278610-81:
(8*2)+(7*7)+(6*8)+(5*6)+(4*1)+(3*0)+(2*8)+(1*1)=164
164 % 10 = 4
So 278610-81-4 is a valid CAS Registry Number.

A dendrimer chiroptical switch based on the reversible intramolecular photoreaction of anthracene and benzene rings

Liu, Wenjie,Cao, Derong,Peng, Jinan,Zhang, Hong,Meier, Herbert

scheme or table, p. 1896 - 1901 (2011/04/12)

A series of Frechet-type dendrimers with 9-benzyloxymethylanthracene cores were synthesized and characterized. The chiral source for the dendrimers was an (S)-2-methyl-1-butoxy group in the 3-position of the benzene ring. Irradiation at 366 nm of a dilute

Polymers with Controlled Molecular Architecture: Control of Surface Functionality in the Synthesis of Dendritic Hyperbranched Macromolecules using the Convergent Approach
