Check Digit Verification of cas no
The CAS Registry Mumber 917-20-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,1 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 917-20:
(5*9)+(4*1)+(3*7)+(2*2)+(1*0)=74
74 % 10 = 4
So 917-20-4 is a valid CAS Registry Number.

Synthesis of new bifluorophoric probes adapted to studies of donor-donor electronic energy transfer in lipid systems
Grechishnikova, Irina V.,Johansson, Lennart B.-A,Molotkovsky, Julian G.
, p. 87 - 98 (2007/10/03)
A series of bifluorophoric fluorescent probes with identical pairs of chromophores have been synthesized. The fluorophores are 9-anthryl, 3-perylenyl and rhodamine 101, and they are separated by a long rigid (bisteroid) or flexible (dotriacontane) diol sp
