Check Digit Verification of cas no

The CAS Registry Mumber 1180667-75-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,0,6,6 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1180667-75:
(9*1)+(8*1)+(7*8)+(6*0)+(5*6)+(4*6)+(3*7)+(2*7)+(1*5)=167
167 % 10 = 7
So 1180667-75-7 is a valid CAS Registry Number.

Quantitative evaluation of anion-π interactions in solution

Gil-Ramirez, Guzman,Escudero-Adan, Eduardo C.,Benet-Buchholz, Jordi,Ballester, Pablo

, p. 4114 - 4118 (2008)

(Figure Presented) Anions included: A series of meso-tetraaryl calix[4]pyrrole receptors have been used as a model system to quantify chloride-π interactions in solution (see picture; green balls are chloride ions). The free energy values are generally indicative of a repulsive interaction; their magnitude depends on the substituent on the aromatic ring.
