Check Digit Verification of cas no

The CAS Registry Mumber 93712-84-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,7,1 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 93712-84:
(7*9)+(6*3)+(5*7)+(4*1)+(3*2)+(2*8)+(1*4)=146
146 % 10 = 6
So 93712-84-6 is a valid CAS Registry Number.

Synthesis and structure of hydrido bis(ethylene) and hydrido dinitrogen complexes of rhenium(I) having dimethylphenylphosphine ligands

Komiya, Sanshiro,Baba, Atsushi

, p. 3105 - 3110 (2008/10/08)

mer-Hydridobis(ethylene)tris(dimethylphenylphosphine)rhenium(I) (1) and cis-hydrido(dinitrogen)-tetrakis(dimethylphenylphosphine)rhenium(I) (2) have been prepared by the reaction of mer-trichloro-tris(dimethylphenylphosphine)rhenium(I) with ethyllithium and n-propyllithium, respectively. X-ray structure analysis reveals that which complexes are octahedral, and in the former complex the two coordinated ethylenes occupy sites perpendicular to each other in cis positions and in the latter complex hydrido and dinitrogen ligands in cis positions. The coordinated ethylene and dinitrogen can be smoothly displaed by dihydrogen to give known trihydrido- or pentahydridorhenium complexes. Crystal data for 1: space group P1, Z = 2, a = 9.285 (3) ?, b = 19.229 (5) ?, c = 9.044 (3) ?, α = 93.47 (3)°, β = 120.16 (2)°, γ = 90.23 (3)°, V = 1392.5 (8) ?3, R = 0.0653, Rw = 0.0641, based on 3959 reflections with F > 3σ(F). Crystal data for 2: space group P21/a, Z = 4, a = 27.49 (1) ?, b = 10.113 (2) ?, c = 12.235 (6) ?, β = 91.94 (4)°, V = 3424 (2) ?3, R = 0.0464, Rw = 0.0533, based on 4129 reflections with F > 3σ(F).
