475089-46-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 475089-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,5,0,8 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 475089-46:
(8*4)+(7*7)+(6*5)+(5*0)+(4*8)+(3*9)+(2*4)+(1*6)=184
184 % 10 = 4
So 475089-46-4 is a valid CAS Registry Number.

The synthesis of deoxyfusapyrone. 1. An approach to the pyrone moiety
Organ, Michael G.,Wang, Junquan
, p. 7847 - 7851 (2007/10/03)
An effective synthesis of the C1-C10 component of deoxyfusapyrone has been achieved that will allow for the synthesis of both the (R) and (S) form of the C-8 chiral center starting from optically pure (+)- and (-)-3,3-dimethyl-2-hydroxy-gammalactone (pantolactone).
