71443-23-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71443-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,4,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71443-23:
(7*7)+(6*1)+(5*4)+(4*4)+(3*3)+(2*2)+(1*3)=107
107 % 10 = 7
So 71443-23-7 is a valid CAS Registry Number.

Silica gel enables Achmatowicz rearrangement with KBr/oxone under “anhydrous” condition for one-pot functionalization

Zhao, Guodong,Tong, Rongbiao

, p. 1669 - 1675 (2019/01/04)

Silica gel was found to effectively promote Achmatowicz rearrangement (AchR) using KBr/oxone under near anhydrous condition. This new protocol allows direct functionalization of AchR products in a one-pot manner, effectively reducing the cost, time, and e

De novo asymmetric bio- and chemocatalytic synthesis of saccharides - Stereoselective formal O-glycoside bond formation using palladium catalysis

Comely, Alex C.,Eelkema, Rienk,Minnaard, Adriaan J.,Feringa, Ben L.

, p. 8714 - 8715 (2007/10/03)

A novel integrated bio- and chemocatalytic approach to the de novo catalytic asymmetric synthesis of saccharides has been developed. Acetoxypyranones obtained enantiopure by enzymatic resolution have been shown to undergo highly stereoselective palladium-catalyzed formal O-glycoside bond formation. The combination of these protocols can be applied to the iterative asymmetric catalytic synthesis of saccharides. Copyright

Montmorillonite K-10 clay catalysed glycosidation of 1-O-acetyl-2,3-dideoxy-DL-pent-2-enopyrano-4-ulose

Shanmugam,Nair

, p. 3007 - 3013 (2007/10/03)

The O-glycosidation reaction of 1-O-acetyl-2,3-dideoxy-DL-pent-2-enopyran-4-ulose catalysed by the environmentally accepted and inexpensive industrial catalyst Montmorillonite K-10 clay with variety of alcohols in high yield is reported.
