Check Digit Verification of cas no
The CAS Registry Mumber 398119-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,9,8,1,1 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 398119-21:
(8*3)+(7*9)+(6*8)+(5*1)+(4*1)+(3*9)+(2*2)+(1*1)=176
176 % 10 = 6
So 398119-21-6 is a valid CAS Registry Number.

A helically folded poly(m,p-phenylene)
Burkhalter, Manuel,Kandre, Ramchandra,Lukin, Oleg
, p. 4132 - 4136 (2015)
Abstract Two amphiphilic poly(m,p-phenylene)s were synthesized through Suzuki polycondensation from 1,3-phenylene dibromide bearing solubilizing tri- or tetra(ethylene glycol) chains and 1,4-phenylene diboronic acid diester. Unlike its tri(ethylene glycol
