Check Digit Verification of cas no
The CAS Registry Mumber 1447738-12-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,7,3 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1447738-12:
(9*1)+(8*4)+(7*4)+(6*7)+(5*7)+(4*3)+(3*8)+(2*1)+(1*2)=186
186 % 10 = 6
So 1447738-12-6 is a valid CAS Registry Number.

Linear porphyrin dimers with fluorenyl arms linked by an ethynyl bridge
Merhi, Areej,Drouet, Samuel,Kerisit, Nicolas,Paul-Roth, Christine O.
, p. 7112 - 7124 (2013)
A series of porphyrin monomers bearing fluorenyl donor groups is presented; successively, compounds 10, 11, 12, and 13 bearing three fluorenyl groups. Starting from these building blocks, the synthesis of new porphyrin ethynyl-linked dimers 7 and 8, beari
