Check Digit Verification of cas no

The CAS Registry Mumber 152291-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,2,9 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 152291-69:
(8*1)+(7*5)+(6*2)+(5*2)+(4*9)+(3*1)+(2*6)+(1*9)=125
125 % 10 = 5
So 152291-69-5 is a valid CAS Registry Number.

Synthesis and crystal structure of the first base-free diarylgermylene-transition metal mononuclear complexes

Tokitoh, Norihiro,Manmaru, Kyoko,Okazaki, Renji

, p. 167 - 171 (1994)

The first base-free diarylgermylene-transition metal mononuclear complexes Tb(Tip)Ge=M-(CO)5 (1, M = W; 2, M = Cr; Tb = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Tip = 2,4,6-triisopropylphenyl) were synthesized by the reaction of a new type of kinetically stabilized diarylgermylene Tb(Tip)Ge: (3), obtained by the treatment of germanium(II) iodide with bulky aryllithiums (TbLi and TipLi), with the corresponding pentacarbonylmetal(0)-tetrahydrofuran complexes of group 6 metals (W and Cr). Of the two diarylgermylene-group 6 metal complexes (1 and 2), the molecular structure of 1 was determined by X-ray crystallographic analysis. Crystal data with Mo Ka radiation (λ = 0.710 69 A?): 1, C47H82GeO5Si6W, triclinic, space group P1, a = 12.490(2) A?, b = 23.890(3) A?, c = 10.254(1) A?, α = 96.21(1)°, β = 105.52(1)°, γ = 89.82(1)°, V = 2930(1) A?3, Z = 2, R = 0.045, Rw = 0.045 based on 8032 reflections with I > 3σ(I) together with 541 variable parameters.
