Check Digit Verification of cas no

The CAS Registry Mumber 153775-72-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,7,7 and 5 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 153775-72:
(8*1)+(7*5)+(6*3)+(5*7)+(4*7)+(3*5)+(2*7)+(1*2)=155
155 % 10 = 5
So 153775-72-5 is a valid CAS Registry Number.

Synthesis and evaluation of new ditopic cyclophane receptors for benzoic acid

Stetson, Christopher M.,Nishikawa, Shiro,Purkiss, David W.,Dalley,Bartsch, Richard A.

, p. 1107 - 1115 (2007/10/03)

As potential receptors for a benzoic acid guest, new ditopic cyclophane host molecules, each with a π electron-rich portion and a pyridine ring-containing portion, are synthesized. Complexation of benzoic acid guest by the potential molecular receptors is probed by infrared spectroscopy, proton magnetic resonance titration experiments and solid-state structure determination.
