Check Digit Verification of cas no

The CAS Registry Mumber 68351-73-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,5 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 68351-73:
(7*6)+(6*8)+(5*3)+(4*5)+(3*1)+(2*7)+(1*3)=145
145 % 10 = 5
So 68351-73-5 is a valid CAS Registry Number.

Ring-Opening Polymerization of Cyclic Phosphonates: Access to Inorganic Polymers with a PV-O Main Chain

Arz, Marius I.,Annibale, Vincent T.,Kelly, Nicole L.,Hanna, John V.,Manners, Ian

supporting information, p. 2894 - 2899 (2019/03/05)

We describe a new class of inorganic polymeric materials featuring a main chain consisting of PV-O bonds and aryl side groups, which was obtained with >70 repeat units by ring-opening polymerization of cyclic phosphonates. This monomer-polymer system was found to be dynamic in solution enabling selective depolymerization under dilute conditions, which can be tuned by varying the substituents. The polymers show high thermal stability to weight loss and can be easily fabricated into self-standing thin films. Structural characterizations of the cyclic 6-and 12-membered ring precursors are also described.
