67453-19-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67453-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,5 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 67453-19:
(7*6)+(6*7)+(5*4)+(4*5)+(3*3)+(2*1)+(1*9)=144
144 % 10 = 4
So 67453-19-4 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
