194800-98-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 194800-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,4,8,0 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 194800-98:
(8*1)+(7*9)+(6*4)+(5*8)+(4*0)+(3*0)+(2*9)+(1*8)=161
161 % 10 = 1
So 194800-98-1 is a valid CAS Registry Number.

A new approach to the pancratistatin C-ring from D-Glucose: Ferrier rearrangement, pseudoinversion and Pd-catalyzed cyclizations

Friestad, Gregory K.,Branchaud, Bruce P.

, p. 5933 - 5936 (2007/10/03)

A Ferrier rearrangement and β-hydroxyketone transposition are key steps in a route to a pancratistatin C-ring precursor. A key feature of the strategy is the pseudoinversion accomplished by β-hydroxyketone transposition, which allows convenient access from methyl α-D-glucopyranoside. Arylations of the C-ring by intramolecular reductive or non-reductive Pd-catalyzed conjugate addition have been demonstrated, utilizing the C1 hydroxyl to deliver the tethered aryl synthon.
