Check Digit Verification of cas no

The CAS Registry Mumber 267237-69-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,7,2,3 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 267237-69:
(8*2)+(7*6)+(6*7)+(5*2)+(4*3)+(3*7)+(2*6)+(1*9)=164
164 % 10 = 4
So 267237-69-4 is a valid CAS Registry Number.

Symmetrical tetra-β″-sulfoleno-meso-aryl-porphyrins-synthesis, spectroscopy and structural characterization

Banala, Srinivas,Wurst, Klaus,Kr?utler, Bernhard

, p. 115 - 122 (2014/04/03)

We report here the preparation (in one-pot) of a tetra-β″- sulfoleno-meso-aryl-porphyrin in about 80% yield by using an optimized modification of Lindsey's variant of the Adler-Longo approach. The Zn(II)-, Cu(II)- and Ni(II)-complexes of the symmetrical p

A symmetrical tetrasulfolenoporphyrin as reactive building block

Kraeutler, Bernhard,Sheehan, Craig S.,Rieder, Alexander

, p. 583 - 591 (2007/10/03)

The efficient preparation of the symmetric tetrasulfolenoporphyrin 1 is reported, which shows good solubility in a variety of solvents. In 1, four sulfone groups that symmetrically bridge the eight methylene groups in β- position at the pyrrole rings prov
