Check Digit Verification of cas no

The CAS Registry Mumber 177349-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,7,3,4 and 9 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 177349-44:
(8*1)+(7*7)+(6*7)+(5*3)+(4*4)+(3*9)+(2*4)+(1*4)=169
169 % 10 = 9
So 177349-44-9 is a valid CAS Registry Number.

Structural studies by exciton coupled circular dichroism over a large distance: Porphyrin derivatives of steroids, dimeric steroids, and brevetoxin B

Matile,Berova,Nakanishi,Fleischhauer,Woody

, p. 5198 - 5206 (1996)

The present study (see ref 1) delineates the scope and limitations of porphyrin chromophores for structural studies by the exciton coupled circular dichroic (CD) method. A distance dependency of the porphyrin coupling was investigated in the range between
