717137-43-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 717137-43-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,1,7,1,3 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 717137-43:
(8*7)+(7*1)+(6*7)+(5*1)+(4*3)+(3*7)+(2*4)+(1*3)=154
154 % 10 = 4
So 717137-43-4 is a valid CAS Registry Number.

Doubly diastereoselective conjugate addition of enantiopure lithium amides to enantiopure N-enoyl oxazolidin-2-ones: A mechanistic probe

Davies, Stephen G.,Fletcher, Ai M.,Hermann, Gesine J.,Poce, Giovanna,Roberts, Paul M.,Smith, Andrew D.,Sweet, Miles J.,Thomson, James E.

experimental part, p. 1635 - 1648 (2010/10/18)

The doubly diastereoselective conjugate addition of the antipodes of lithium N-benzyl-N-(α-methylbenzyl)amide to a range of enantiopure N-enoyl oxazolidin-2-ones has been used as a mechanistic probe to determine that the reactive conformation is the anti-s-cis form. The β-amino carbonyl products resulting from these conjugate addition reactions are useful templates for further elaboration into an α,β,α-pseudotripeptide.
