Check Digit Verification of cas no

The CAS Registry Mumber 1423187-15-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,3,1,8 and 7 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1423187-15:
(9*1)+(8*4)+(7*2)+(6*3)+(5*1)+(4*8)+(3*7)+(2*1)+(1*5)=138
138 % 10 = 8
So 1423187-15-8 is a valid CAS Registry Number.

Synthesis and structures of triple-decker complexes with a bridging tetramethylcyclopentadienyl ligand

Ghag, Sonam K.,Tarlton, Michael L.,Henle, Ernst A.,Ochoa, Elizabeth M.,Watson, Alex W.,Zakharov, Lev N.,Watson, Eric J.

, p. 1851 - 1857 (2013)

New triple-decker complexes with bridging tetramethylcyclopentadienyl ligands were synthesized by the reaction of electrophilic metal fragments with octamethylferrocene, Cp′2Fe (Cp′ = C5Me 4H). The reaction of coordinatively unsaturated ruthenium cations [(C5R5)Ru]+ (R = H, CH3) with Cp′2Fe afforded purple-colored heterometallic triple-decker complexes [(C5R5)Ru(μ-Cp′)FeCp′] + by direct electrophilic addition. Surprisingly, the analogous reaction with the coordinatively unsaturated manganese cation [Mn(CO) 3]+ and Cp′2Fe produced a blue homometallic triple-decker complex, [Cp′Fe(μ-Cp′)FeCp′] +, by ring abstraction and subsequent addition of the newly generated cation [Cp′Fe]+ to an equivalent of Cp′2Fe. Three air-stable triple-decker complexes, [Cp′Fe(μ-Cp′) FeCp′]+ (2), [CpRu(μ-Cp′)FeCp′]+ (3), and [Cp*Ru(μ-Cp′)FeCp′]+ (4), have been characterized by NMR spectroscopy, elemental analysis, and single-crystal X-ray diffraction.
