Check Digit Verification of cas no

The CAS Registry Mumber 167026-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,7,0,2 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 167026-72:
(8*1)+(7*6)+(6*7)+(5*0)+(4*2)+(3*6)+(2*7)+(1*2)=134
134 % 10 = 4
So 167026-72-4 is a valid CAS Registry Number.

Amphiphilic Terpyridine Complexes of Ruthenium and Rhodium displaying Lyotropic Mesomorphism

Holbrey, John D.,Tiddy, Gordon J. T.,Bruce, Duncan W.

, p. 1769 - 1774 (1995)

New 4'-alkyl-substituted 2,2':6',2''-terpyridine (4'R-terpy) compounds have been synthesised from 4'-methyl-2,2':6',2''-terpyridine and an appropriate 1-bromoalkane and complexed with ruthenium and rhodium to yield new bis(terpyridine) complexes (2+) (R = C19H39 or C31H63) and (3+) (R = C19H39) as chloride and hexafluorophosphate salts.These complexes are amphiphilic being structurally related to surfactant tris(bipyridine)ruthenium complexes.Both ruthenium and rhodium complexes with R = C19H39 and chloride counter ions show lyotropic mesomorphism in water, and the ruthenium complex with R = C31H63 shows mesophase formation in ethylene glycol.
