Check Digit Verification of cas no

The CAS Registry Mumber 1015473-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,1,5,4,7 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1015473-19:
(9*1)+(8*0)+(7*1)+(6*5)+(5*4)+(4*7)+(3*3)+(2*1)+(1*9)=114
114 % 10 = 4
So 1015473-19-4 is a valid CAS Registry Number.

Symmetrical and unsymmetrical ferrocenyl perylenediimides: Design, synthesis and properties

Dhokale, Bhausaheb,Jadhav, Thaksen,Patil, Yuvraj,Misra, Rajneesh

, p. 164 - 170 (2016)

Symmetrical and unsymmetrical ferrocenyl perylenediimides (PDIs) 1–6 were designed and synthesized by the Sonogashira cross-coupling and nucleophilic aromatic substitution (SNAr) reactions. The PDIs were functionalized with ferrocenyl moiety through varying spacers to study the effect of one and two ferrocenyl units on their photophysical and electrochemical properties. The ferrocenyl unit and PDI were coupled through 3-phenylacetylene, 4-phenylacetylene and 4-phenoxy linkages to tune the electronic properties. The ferrocenyl PDIs show red shift in the absorption with the increasing conjugation. The efficient electronic communication between the ferrocenyl unit and PDI leads to the strong charge-transfer from donor ferrocene to the acceptor PDI core and quenching of fluorescence. The electrochemical studies reveal the effect of spacers on the Donor-Acceptor (D-A) interactions and electronic energy levels. The oxidation of ferrocenyl PDIs 1–6 are harder than free ferrocene indicating the considerable delocalization of ferrocenyl electrons on the PDI moiety. The experimental observations were adequately supported by theoretical calculations.
