Check Digit Verification of cas no

The CAS Registry Mumber 1228338-63-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,3,3 and 8 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1228338-63:
(9*1)+(8*2)+(7*2)+(6*8)+(5*3)+(4*3)+(3*8)+(2*6)+(1*3)=153
153 % 10 = 3
So 1228338-63-3 is a valid CAS Registry Number.

PH-responsive molecular tweezers

Leblond, Jeanne,Gao, Hui,Petitjean, Anne,Leroux, Jean-Christophe

, p. 8544 - 8545 (2010)

Molecular tweezers are dynamic devices that are able to switch from one conformation to another upon stimulation by an external trigger. In this work, we report a new water-soluble macromolecular carrier bearing a pH-responsive molecular tweezer, whose affinity for a substrate depends on the external pH. The conformational change of the switching unit was evidenced by 1H NMR spectroscopy, and fluorescence studies conducted in aqueous media demonstrated the ability of the carrier to bind to substrates in a pH-dependent fashion.
