Check Digit Verification of cas no

The CAS Registry Mumber 228422-24-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,8,4,2 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 228422-24:
(8*2)+(7*2)+(6*8)+(5*4)+(4*2)+(3*2)+(2*2)+(1*4)=120
120 % 10 = 0
So 228422-24-0 is a valid CAS Registry Number.

Precursors for the production of chiral 1,3-aminoalcohols

-

, (2008/06/13)

The disclosure describes novel precursors for the preparation of chiral 1,3-aminoalcohols. The precursors are chiral 4-hydroxycarboxamides, 4-hydroxyhydroxamic acids, or 4-hydroxyhydrazides produced from chiral gamma-lactones, which in turn are derived from 1,4-diols by stereoselective oxidation. The chiral 4-hydroxycarboxamides, 4-hydroxyhydroxamic acids, or 4-hydroxyhydrazides are converted into chiral 1,3-aminoalcohols by stereospecific rearrangement.
