917246-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 917246-58-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,7,2,4 and 6 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 917246-58:
(8*9)+(7*1)+(6*7)+(5*2)+(4*4)+(3*6)+(2*5)+(1*8)=183
183 % 10 = 3
So 917246-58-3 is a valid CAS Registry Number.

Pd-catalysed domino arylation/CH activation for the synthesis of acenaphthylenes
Tietze, Lutz F.,Lotz, Florian
, p. 4676 - 4684 (2007/10/03)
The palladium-catalysed domino cyclisation of the aryl bromides 4, containing an alkyne and a bromonaphthyl moiety, leads to tetracycles of type 5 in good yields. The substrates 4 are easily accessible by addition of the corresponding lithiated alkynes 7
