Check Digit Verification of cas no

The CAS Registry Mumber 1220999-80-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,9,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1220999-80:
(9*1)+(8*2)+(7*2)+(6*0)+(5*9)+(4*9)+(3*9)+(2*8)+(1*0)=163
163 % 10 = 3
So 1220999-80-3 is a valid CAS Registry Number.

Chiral, non-racemic diols, and α-amino acid-derived β-amino alcohols as templates for chiral catalysts in the Tsuji-Trost reaction

Mahadik, Geetanjali S.,Hitchcock, Shawn R.

experimental part, p. 33 - 38 (2010/04/24)

A commercially available collection of β-amino alcohols have been converted to their corresponding β-(o-diphenylphosphino) benzoyloxy(o-diphenylphosphino) benzamides and have been employed in the Tsuji-Trost asymmetric alkylation reaction with 1,3-diphenylpropenyl acetate. The best ligand was derived from l-tert-leucinol and when applied to the asymmetric allylic alkylation reaction, yielded the product in an enantiomeric ratio of 99.5:0.5 favoring the (S)-enantiomer.
