191403-45-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 191403-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,1,4,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 191403-45:
(8*1)+(7*9)+(6*1)+(5*4)+(4*0)+(3*3)+(2*4)+(1*5)=119
119 % 10 = 9
So 191403-45-9 is a valid CAS Registry Number.

A tetraaryldigermene with a short germanium-germanium double bond and a nearly planar environment of both germanium atoms

Weidenbruch, Manfred,Stiirmann, Martin,Kilian, Hartmut,Fohl, Siegfried,Saak, Wolfgang

, p. 735 - 738 (2007/10/03)

Treatment of GeCl2 ·dioxane with the Grignard reagent RMgBr (R = 2-rBu-4,5.6-Me3C6H) furnishes the tetraaryldigermene R2Ge=GeR2 (8). X-ray structure-analysis of 8 reveals a short Ge=Ge double bond, a nearly planar environment of both germanium atoms and extremely widened C-Ge-C angles of 128°. In solution, 8 dissociates into two germylene molecules R2Ge: which can be trapped with oxygen or by [4 + 1] cycloaddition reactions with 1,4-dihetero1,3-dienes. A similar cycloadduct of a stannylene was obtained by thermolysis of (R′2Sn)3 (R′ = 2,4,6-JPr3C6H2), in the presence of a 1,4-diazabutadiene and characterized by an Xray structure-analysis.
