123533-30-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123533-30-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,5,3 and 3 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123533-30:
(8*1)+(7*2)+(6*3)+(5*5)+(4*3)+(3*3)+(2*3)+(1*0)=92
92 % 10 = 2
So 123533-30-2 is a valid CAS Registry Number.

A FORMATION OF OPTICALLY ACTIVE OXETANES FROM SUGARS BY BORON TRIFLUORIDE CATALYZED CYCLOADDITION REACTION
Sugimura, Hideyuki,Osumi, Kenji
, p. 1571 - 1574 (2007/10/02)
Boron trifluoride etherate catalyzed the formal cycloaddition of 2,3-O-isopropylidene derivatives of aldehyde-D-aldose with enol ethers, vinyl sulfide, and disubstituted terminal olefins to afford chiral oxetanes.
