Check Digit Verification of cas no

The CAS Registry Mumber 1352955-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,9,5 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1352955-20:
(9*1)+(8*3)+(7*5)+(6*2)+(5*9)+(4*5)+(3*5)+(2*2)+(1*0)=164
164 % 10 = 4
So 1352955-20-4 is a valid CAS Registry Number.

Branched cationic polyurethane prepared by polyaddition of chloromethylated five-membered cyclic carbonate and diethylenetriamine in molten salts

Ochiai, Bungo,Koda, Kazuhiro,Endo, Takeshi

, p. 47 - 51 (2012)

A branched cationic polymer was synthesized by polyaddition of 4-chloromethyl-1,3-dioxolan-2-one and diethylenetriamine in molten salts. The polyaddition proceeded through nucleophilic addition of the primary amino group to the cyclic carbonate structure and quarternization of the secondary amino group with the chloromethyl group. The resulting cationic polymer was a good and recyclable catalyst for the reaction of carbon dioxide and epoxides owing to the ammonium structure. The complexation with DNA was confirmed by dynamic light scattering and zeta potential measurements, and it suggests the potential application as a carrier for drug delivery system.
