489432-97-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 489432-97-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,9,4,3 and 2 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 489432-97:
(8*4)+(7*8)+(6*9)+(5*4)+(4*3)+(3*2)+(2*9)+(1*7)=205
205 % 10 = 5
So 489432-97-5 is a valid CAS Registry Number.

One-step syntheses of styryl germatranes via rhodium- or palladium-catalyzed hydrogermylation of arylacetylenes by HGe(OCH2CH2)3N
Faller,Kultyshev, Roman G.
, p. 199 - 202 (2008/10/08)
The addition of germatrane, HGe(OCH2CH2)3N (1), to terminal acetylenes is catalyzed by [Cp*RhCl2]2 and yields styrylgermatranes. The stereochemistry of the double bond can be controlled by the choice
