153230-42-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153230-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,2,3 and 0 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 153230-42:
(8*1)+(7*5)+(6*3)+(5*2)+(4*3)+(3*0)+(2*4)+(1*2)=93
93 % 10 = 3
So 153230-42-3 is a valid CAS Registry Number.

Synthesis of carbohydrates via tandem use of the osmium-catalyzed asymmetric dihydroxylation and enzyme-catalyzed aldol addition reactions

Henderson, Ian,Sharpless, K. Barry,Wong, Chi-Huey

, p. 558 - 561 (2007/10/02)

A new strategy is described for the asymmetric synthesis of carbohydrate derivatives via the tandem use of the osmium-catalyzed asymmetric dihydroxylation (AD) and aldolase-catalyzed aldol addition reactions. Both D- and L-forms of fructose, 6-deoxy-galacto-2-heptulose, and 6-phenyl-galacto-2-hexulose were synthesized to illustrate this methodology.
