Check Digit Verification of cas no

The CAS Registry Mumber 1374220-23-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,4,2,2 and 0 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1374220-23:
(9*1)+(8*3)+(7*7)+(6*4)+(5*2)+(4*2)+(3*0)+(2*2)+(1*3)=131
131 % 10 = 1
So 1374220-23-1 is a valid CAS Registry Number.

Tubular conjugated polymer for chemosensory applications

Molad, Anat,Goldberg, Israel,Vigalok, Arkadi

supporting information; experimental part, p. 7290 - 7292 (2012/06/16)

In this paper, we present the concept of a soluble tubular conjugated polymer (TCP). We report on a fluorescent 5,5′-Bicalixarene-based polymer where the calixarene units are seamlessly incorporated in the conjugated polymeric chain that can respond to a small molecule complexation inside the hydrophobic cavity. In particular, our system demonstrated a reversible rapid fluorescence quenching upon interaction of gaseous nitric oxide with the calixarene moiety.
