1447732-05-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1447732-05-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,7,3 and 2 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1447732-05:
(9*1)+(8*4)+(7*4)+(6*7)+(5*7)+(4*3)+(3*2)+(2*0)+(1*5)=169
169 % 10 = 9
So 1447732-05-9 is a valid CAS Registry Number.

Stereoselective synthesis of the C13-32 spiroacetal fragment of spirangien A
Gregg, Claire,Perkins, Michael V.
, p. 6845 - 6854 (2013/07/26)
Stereoselective synthesis of an advanced intermediate towards the highly cytotoxic polyketide metabolite spirangien A was achieved. A key step in the synthesis was installation of the C23 stereocentre by a substrate controlled C22-23 aldol reaction. Compa
