Check Digit Verification of cas no

The CAS Registry Mumber 62987-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,9,8 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 62987-07:
(7*6)+(6*2)+(5*9)+(4*8)+(3*7)+(2*0)+(1*7)=159
159 % 10 = 9
So 62987-07-9 is a valid CAS Registry Number.

A general route for the synthesis of flexible porphyrin dimers

Twyman, Lance J.,Sanders, Jeremy K. M.

, p. 6681 - 6684 (2007/10/03)

The synthesis of two cyclic porphyrin dimers is reported. In each case the porphyrins are connected by a rigid butadiyne link, and a flexible alkyl chain tether. The length of this tether controls both the porphyrin-porphyrin distance, and porphyrin-porphyrin geometry. It is hoped that the extra flexibility designed within these molecules will enable them to act as general catalytic hosts for future study.

Vibrational and electronic spectra of new liposoluble metalloporphyrins in a nonpolar noncoordinating solvent

Ringuet, Michel,Girard, Denis,Chapados, Camille

, p. 1070 - 1079 (2007/10/02)

A new liposoluble porphyrin, 2,7,12,17-tetrahexyl-3,8,13,18-tetramethylporphin (THTMP), and its complexes with divalent (Mg, Co, Ni, Cu, Zn, Cd, Hg) and trivalent (Mn, Fe) metals have been synthesized.The electronic, infrared, and far-infrared spectra of
