128298-81-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 128298-81-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,2,9 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 128298-81:
(8*1)+(7*2)+(6*8)+(5*2)+(4*9)+(3*8)+(2*8)+(1*1)=157
157 % 10 = 7
So 128298-81-7 is a valid CAS Registry Number.

Preparation of α-oxygenated ketones by the dioxygenation of alkenyl boronic acids

Patil, Aditi S.,Mo, Dong-Liang,Wang, Heng-Yen,Mueller, Daniel S.,Anderson, Laura L.

supporting information; experimental part, p. 7799 - 7803 (2012/09/08)

Two in two: Dioxygenation of alkenyl boronic acids has been achieved with N-hydroxyphthalimide. The two-step process involves etherification of an alkenyl boronic acid with N-hydroxyphthalimide followed by a [3,3] rearrangement. The dioxygenated product can then be hydrolyzed to form either the corresponding α-hydroxy ketone or the α-benzoyloxy ketone. Copyright

Synthesis of α-hydroxy ketones using a HOF·MeCN complex

Rozen, Shlomo,Bareket, Yifat

, p. 627 - 628 (2007/10/03)

The complex, HOF·MeCN made directly by bubbling fluorine through aqueous acetonitrile, reacts quickly and efficiently with enolic forms of ketones to produce α-hydroxy ketones.

Chiral products via asymmetric deprotonation of 4-tert-butylcyclohexanone using chiral lithium amide bases

Cousins,Simpkins

, p. 7241 - 7244 (2007/10/02)

The asymmetric deprotonation of 4-tert-butylcyclohexanone using chiral lithium amide bases gives derived silyl enol ether products in up to 88% ee.
