Check Digit Verification of cas no

The CAS Registry Mumber 1192944-48-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,2,9,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1192944-48:
(9*1)+(8*1)+(7*9)+(6*2)+(5*9)+(4*4)+(3*4)+(2*4)+(1*8)=181
181 % 10 = 1
So 1192944-48-1 is a valid CAS Registry Number.

Improvements and Applications of the Transition Metal-Free Asymmetric Allylic Alkylation using Grignard Reagents and Magnesium Alanates

Grassi, David,Alexakis, Alexandre

supporting information, p. 3171 - 3186 (2015/11/03)

Two new N-heterocyclic carbene (NHC) ligands have been synthesized and employed in the transition metal-free asymmetric allylic alkylation (AAA) mediated by Grignard reagents and magnesium alanates. The employment of these ligands showed high yields and improved regio- and enantioselectivity in the formation of tertiary and quaternary stereocenters. Moreover, the low catalyst loading (up to 0.3 mol%) and high scalability (up to 10 mmol) of this improved methodology provide a convenient access to biologically active compounds and synthetically valuable intermediates.
