291780-71-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 291780-71-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,1,7,8 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 291780-71:
(8*2)+(7*9)+(6*1)+(5*7)+(4*8)+(3*0)+(2*7)+(1*1)=167
167 % 10 = 7
So 291780-71-7 is a valid CAS Registry Number.

A porphyrin square: Synthesis of a square-shaped π-conjugated porphyrin tetramer connected by diacetylene linkages

Sugiura, Ken-Ichi,Fujimoto, Yoshinobu,Sakata, Yoshiteru

, p. 1105 - 1106 (2000)

A square-shaped π-conjugated porphyrin tetramer has prepared: the excitation energies of both the Soret and Q bands, 19 880 (503) and 15 180 cm-1 (659 nm), respectively, are quite low compared with those for the monomer and reported cyclic porphyrin oligomers.
