Check Digit Verification of cas no
The CAS Registry Mumber 1173023-24-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,0,2 and 3 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1173023-24:
(9*1)+(8*1)+(7*7)+(6*3)+(5*0)+(4*2)+(3*3)+(2*2)+(1*4)=109
109 % 10 = 9
So 1173023-24-9 is a valid CAS Registry Number.

Enantioselective Rhodium-Catalyzed Atom-Economical Macrolactonization
Ganss, Stephanie,Breit, Bernhard
, p. 9738 - 9742 (2016)
A highly attractive route toward macrolactones, which form the cyclic scaffold of a multitude of diverse natural compounds, is described. Although many chemical approaches to this structural motif have been explored, an asymmetric variant of the cyclization is unprecedented. Herein we present an enantioselective macrolactonization through an intramolecular atom-economical rhodium-catalyzed coupling of ω-allenyl-substituted carboxylic acids. The use of a modified diop ligand, chiral DTBM-diop, led to high enantioselectivity (up to 93 % ee). The reaction tolerated a large variety of functionalities, including α,β-unsaturated carboxylic acids and depsipeptides, and provided the desired macrocycles with very high enantio- and diastereoselectivity.
