348621-30-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 348621-30-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,8,6,2 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 348621-30:
(8*3)+(7*4)+(6*8)+(5*6)+(4*2)+(3*1)+(2*3)+(1*0)=147
147 % 10 = 7
So 348621-30-7 is a valid CAS Registry Number.

Synthesis of photo- and electroactive stilbenoid dendrimers carrying dibutylamino peripheral groups

Segura, Jose L.,Gomez, Rafael,Martin, Nazario,Guldi, Dirk M.

, p. 2645 - 2647 (2001)

(Equation presented) A novel convergent synthetic route for the preparation of functionalized and fluorescent stilbenoid dendrons built on the 1,3,5-benzene core and endowed with a periphery of dibutylamino groups has been developed. Long alkyl chains hav

Synthesis, characterization, and optical response of dipolar and non-dipolar poly(phenylenevinylene) dendrimers

Diez-Barra,Garcia-Martinez,Merino,Del Rey,Rodriguez-Lopez,Sanchez-Verdu,Tejeda

, p. 5664 - 5670 (2007/10/03)

New dipolar and non-dipolar poly(phenylenevinylene) dendrimers bearing electron-donating and electron-withdrawing groups have been efficiently synthesized using Heck and Horner-Wadsworth-Emmons reactions. The photoluminescence of these systems may be tuned in the blue zone by choosing the appropriate peripheral groups. Despite the meta-substitution pattern, large Stokes shifts can be observed when π-donor and π-acceptor groups are connected by a m-phenylenevinylene system.
