Check Digit Verification of cas no

The CAS Registry Mumber 849667-83-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,9,6,6 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 849667-83:
(8*8)+(7*4)+(6*9)+(5*6)+(4*6)+(3*7)+(2*8)+(1*3)=240
240 % 10 = 0
So 849667-83-0 is a valid CAS Registry Number.

1H NMR spectral evidence for a specific host-guest complexation induced charge localization in squaraine dyes

Ajayaghosh, Ayyappanpillai,Arunkumar, Easwaran

, p. 3135 - 3138 (2005)

(Chemical Equation Presented) Experimental support is provided for the charge localization in squaraines, a class of fundamentally and technologically important organic dyes, by 1H NMR analysis through a host-guest complexation approach. Specific binding of Ca2+ ions to the squaraine 2 with a podand sidearm resulted in a charge-localized structure 2a with dramatic shifts and resolution of the proton signals when compared to those of 2.
