228262-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 228262-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,2,6 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 228262-80:
(8*2)+(7*2)+(6*8)+(5*2)+(4*6)+(3*2)+(2*8)+(1*0)=134
134 % 10 = 4
So 228262-80-4 is a valid CAS Registry Number.

Synthesis of pinnaic acid; asymmetric construction of spirocyclic core
Arimoto, Hirokazu,Asano, Shigehiro,Uemura, Daisuke
, p. 3583 - 3586 (2007/10/03)
An asymmetric synthesis of the spirocyclic core of pinnaic acid, a cPLA2 inhibitor, is described. A key transformation in the sequence involves an asymmetric Michael-initiated ring closure.
