444809-27-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 444809-27-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,4,8,0 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 444809-27:
(8*4)+(7*4)+(6*4)+(5*8)+(4*0)+(3*9)+(2*2)+(1*7)=162
162 % 10 = 2
So 444809-27-2 is a valid CAS Registry Number.

Convergent enantioselective synthesis of the tricyclic core of phomactin A
Mohr, Peter J.,Halcomb, Randall L.
, p. 2413 - 2416 (2007/10/03)
(Matrix Presented) The tricyclic core of phomactin A was synthesized from 6,6-dimethyl-2-cyclohexen-1-one. Key reactions include the addition of a cyclohexenyllithium reagent to an epoxyaldehyde and a regioselective intramolecular epoxide opening to insta
