Check Digit Verification of cas no

The CAS Registry Mumber 1303477-72-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,3,4,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1303477-72:
(9*1)+(8*3)+(7*0)+(6*3)+(5*4)+(4*7)+(3*7)+(2*7)+(1*2)=136
136 % 10 = 6
So 1303477-72-6 is a valid CAS Registry Number.

Synthesis of π-expanded O-chelated boron-dipyrromethene as an NIR dye

, p. 3187 - 3193 (2011/05/30)

A π-expanded BODIPY dye with an intramolecular boronate skeleton was synthesized by retro Diels-Alder reaction of the bicyclo[2.2.2]octadiene (BCOD)-fused BODIPY and the subsequent O-chelation. The photophysical and electrochemical properties were examined by UV-vis, fluorescence, CV measurements, and DFT calculation. This BODIPY exhibited the absorption and emission over a visible-NIR region at 600-850 nm. O-chelated BODIPY showed a bathocromic shift compared to F-BODIPYs. This dye showed a bright fluorescence emission at 733 nm with the high Φ value of 0.58.
