Check Digit Verification of cas no

The CAS Registry Mumber 160681-96-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,8 and 1 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 160681-96:
(8*1)+(7*6)+(6*0)+(5*6)+(4*8)+(3*1)+(2*9)+(1*6)=139
139 % 10 = 9
So 160681-96-9 is a valid CAS Registry Number.

Porphyrin building blocks for modular construction of bioorganic model systems

Lindsey, Jonathan S.,Prathapan, Sreedharan,Johnson, Thomas E.,Wagner, Richard W.

, p. 8941 - 8968 (2007/10/02)

We outline a modular building block strategy for the covalent assembly of porphyrin-containing model systems. Molecular design issues for the synthesis of porphyrin dimers, dye-porphyrin dyads, and multi-porphyrin arrays have been used to guide the develo
