Check Digit Verification of cas no

The CAS Registry Mumber 340023-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,0,2 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 340023-90:
(8*3)+(7*4)+(6*0)+(5*0)+(4*2)+(3*3)+(2*9)+(1*0)=87
87 % 10 = 7
So 340023-90-7 is a valid CAS Registry Number.

New β-linked pyrrole monomers: Approaches to highly stable and conductive electrochromic polymers

Nadeau, Jocelyn M.,Swager, Timothy M.

, p. 7141 - 7146 (2007/10/03)

An efficient synthetic route to β-linked dipyrrole monomers has been developed. Electrochemical polymerization of these monomers leads to the incorporation of polycyclic aromatic residues into a polymer backbone. The resulting conjugated polymer films are

Synthesis of β,β′-(phenylene)diporphyrins

Fumoto,Uno,Tanaka,Tanaka,Murashima,Ono

, p. 399 - 402 (2007/10/03)

meso-Unsubstituted porphyrin dimers linked with 1,3- and 1,4-phenylenes were prepared from the corresponding phenylenedipyrroles by double [3+1] MacDonald condensation in 16% and 27% yields, respectively. These dipyrroles were in turn prepared from tere- and iso-phthalaldehydes in respective yields of 23% and 41% via the 3-step reactions involving the modified Barton-Zard reaction.
