Check Digit Verification of cas no

The CAS Registry Mumber 118270-56-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,2,7 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118270-56:
(8*1)+(7*1)+(6*8)+(5*2)+(4*7)+(3*0)+(2*5)+(1*6)=117
117 % 10 = 7
So 118270-56-7 is a valid CAS Registry Number.

Polyselenonium salts: Synthesis through sequential selenium-epoxy 'click' chemistry and Se-alkylation

Eom, Taejun,Khan, Anzar

, p. 14271 - 14274 (2020/11/24)

With the help of amphiphilic homopolymers, this work explores three new avenues in polymer chemistry: (i) the 'click' nature of the selenium-epoxy reaction, (ii) alkylation of the seleno-ethers as a means to prepare cationic polyelectrolytes, and (iii) the antibacterial activity of polyselenonium salts.
