The CAS Registry Mumber 24223-07-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,2,2 and 3 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 24223-07:
(7*2)+(6*4)+(5*2)+(4*2)+(3*3)+(2*0)+(1*7)=72
72 % 10 = 2
So 24223-07-2 is a valid CAS Registry Number.

Preparation and a novel rearrangement reaction of 1,2,3,4-tetrahydro-9- hydroxy-β-carboline, and their applications for the total synthesis of (±)- coerulescine

, p. 7 - 10 (2007/10/03)

Novel 9-hydroxy-β-carboline derivatives were produced for the first time. A novel rearrangement reaction of 1,2,3,4-tetrahydro-9-hydroxy-β- carbolines was discovered to give 3,3-disubstituted oxindoles, which was successfully applied to the total synthesis of (±)-coerulescine.
