24341-01-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24341-01-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,4 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 24341-01:
(7*2)+(6*4)+(5*3)+(4*4)+(3*1)+(2*0)+(1*1)=73
73 % 10 = 3
So 24341-01-3 is a valid CAS Registry Number.

Aggregation Studies of Lithium Dialkylamides. The Role of Aggregates in the Carbonylation Reaction

Nudelman, N. S.,Lewkowicz, E.,Furlong, J. J. P.

, p. 1847 - 1852 (1993)

13C NMR spectroscopy and isotopic exchange in carbonylation intermediates have been successfully employed to characterize aggregation of lithium dialkylamides in THF solution.It is shown that lithium (3-oxapentamethylene)amide forms a 1 : 1 mixed aggregate with morpholine.The aggregate remains even in diluted THF solution.Lithium pentamethyleneamide also forms aggregates with piperidine while the less acidic amines do not form mixed aggregates with the corresponding lithium dialkylamide either in the solid state or in THF solution.The product composition in the carbonylation reaction of lithium dialkylamides is highly dependent on their aggregation states, and this phenomenon can be successfully used for synthetic purposes.
