1372147-81-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1372147-81-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,1,4 and 7 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1372147-81:
(9*1)+(8*3)+(7*7)+(6*2)+(5*1)+(4*4)+(3*7)+(2*8)+(1*1)=153
153 % 10 = 3
So 1372147-81-3 is a valid CAS Registry Number.

Synthesis of novel 2H-spiro[1-benzofuran-3,4′-piperidin]ol scaffolds
Leflemme, Nicolas,Stoit, Axel R.,Borghese, Alfio
, p. 2432 - 2435 (2012/06/01)
With the aim to enrich our 'privileged structure'-based library, novel 2H-spiro[1-benzofuran-3,4′-piperidin]ol scaffolds were prepared. The method involved a key intramolecular Heck cyclization which was successfully applied for three series of compounds.
