Check Digit Verification of cas no
The CAS Registry Mumber 32521-09-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,2,5,2 and 1 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 32521-09:
(7*3)+(6*2)+(5*5)+(4*2)+(3*1)+(2*0)+(1*9)=78
78 % 10 = 8
So 32521-09-8 is a valid CAS Registry Number.

Sequential hydrostannylation-cyclisation of δ- and ω-allenyl aryl halides. Cyclisation at the proximal carbon
Grigg, Ronald,Sansano, Jose M.
, p. 13441 - 13454 (2007/10/03)
Palladium catalysed hydrostannylation of (Bu3SnH, THF, O°C) of δ- and ω-allenyl aryl halides followed by mono- or bis-cyclisation (MeCN, 80°C) affords small (5-7), large (11-17) and spirocyclic rings in which cyclisation occurs at the proximal
