926906-98-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 926906-98-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,6,9,0 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 926906-98:
(8*9)+(7*2)+(6*6)+(5*9)+(4*0)+(3*6)+(2*9)+(1*8)=211
211 % 10 = 1
So 926906-98-1 is a valid CAS Registry Number.

Regioselective cycloaddition of o-quinone 4 and protected sinapyl alcohol 2 gave 1,4-benzodioxane 5, which was converted to (±)-nitidanin (6), an antimalarial compound. Two novel procedures were developed to determine the location of the side chains of th

Total synthesis of cleomiscosin C via a regioselective cycloaddition reaction of o-quinone

Kuboki, Atsuhito,Maeda, Chie,Arishige, Tetsuya,Kuyama, Kohei,Hamabata, Mami,Ohira, Susumu

, p. 4516 - 4518 (2008/09/21)

We have achieved total synthesis of cleomiscosin C (aquillochin) through regioselective cycloaddition of o-quinone and protected sinapyl alcohol as a key step. During preparation of o-quinone from phenol by IBX oxidation, silyl substituents adjacent to the phenolic hydroxyl group afforded effective inhibition of an undesired oxidative elimination.
