581782-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 581782-83-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,8,1,7,8 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 581782-83:
(8*5)+(7*8)+(6*1)+(5*7)+(4*8)+(3*2)+(2*8)+(1*3)=194
194 % 10 = 4
So 581782-83-4 is a valid CAS Registry Number.

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
