Check Digit Verification of cas no

The CAS Registry Mumber 1055877-98-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,5,8,7 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1055877-98:
(9*1)+(8*0)+(7*5)+(6*5)+(5*8)+(4*7)+(3*7)+(2*9)+(1*8)=189
189 % 10 = 9
So 1055877-98-9 is a valid CAS Registry Number.

Hollow porphyrin prisms: Modular formation of permanent, torsionally rigid nanostructures via templated olefin metathesis

Youm, Kyoung-Tae,Nguyen, SonBinh T.,Hupp, Joseph T.

supporting information; experimental part, p. 3375 - 3377 (2009/02/06)

Hollow, hexa-porphyrin prisms of two sizes were template-assembled and covalently locked, via cross-olefin metathesis, into permanent, torsionally rigid structures whose active sites (metal sites) can be both accessed and altered in a facile manner. The Royal Society of Chemistry.
