172995-38-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 172995-38-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,9 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 172995-38:
(8*1)+(7*7)+(6*2)+(5*9)+(4*9)+(3*5)+(2*3)+(1*8)=179
179 % 10 = 9
So 172995-38-9 is a valid CAS Registry Number.

Synthesis of β-dimorphecolic acid exploiting highly stereoselective reduction of a side-chain carbonyl group in a π-allyltricarbonyliron lactone complex

Ley, Steven V.,Meek, Graham

, p. 1125 - 1133 (2007/10/03)

A highly enantioselective synthesis of β-dimorphecolic acid 1 is reported. The synthesis features a diastereoselective reduction of the ketone 4, in which the tricarbonyliron lactone tether induces a 1,5 transfer of chirality, followed by a stereoselectiv

Synthesis of β-dimorphecolic acid exploiting highly stereoselective-reduction of a side-chain carbonyl group in a π-allyltricarbonyliron lactone complex

Ley,Meek

, p. 1751 - 1752 (2007/10/02)

A highly stereoselective synthesis of β-dimorphecolic acid is accomplished utilising a π-allyltricarbonyliron lactone complex 3 to control the formation of all the stereochemical features of the natural product.
