490020-98-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 490020-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,0,0,2 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 490020-98:
(8*4)+(7*9)+(6*0)+(5*0)+(4*2)+(3*0)+(2*9)+(1*8)=129
129 % 10 = 9
So 490020-98-9 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
