127492-00-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127492-00-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,9 and 2 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127492-00:
(8*1)+(7*2)+(6*7)+(5*4)+(4*9)+(3*2)+(2*0)+(1*0)=126
126 % 10 = 6
So 127492-00-6 is a valid CAS Registry Number.

A New and Efficient Asymmetric Synthesis of an A-Ring Precursor to Physiologically Active 1α-Hydroxyvitamin D3 Steroids

Posner, Gary H.,Carry, Jean-Christophe,Anjeh, Tizah E. N.,French, Andrew N.

, p. 7012 - 7014 (1992)

A highly stereocontrolled and mild Diels-Alder cycloaddition involving stereochemically matched pyrone (S)-lactate 4 and Lewis acid (-)-Pr(hfc)3 produced bicyclic lactone endo-5 via a double stereodifferentiation process.Bicyclic lactone 5 was then transf

Binaphthol-titanium-promoted, highly enantiocontrolled, Diels-Alder cycloadditions of electronically matched 2-pyrones and vinyl ethers: Streamlined asymmetric synthesis of an A-ring precursor to physiologically active 1α-hydroxyvitamin D3 ster

Posner,Eydoux,Lee,Bull

, p. 7541 - 7544 (2007/10/02)

Bicyclic lactones 4, A-ring precursors to diverse physiologically active 1α-hydroxyvitamin D3 analogs, were prepared in excellent yields and enantiomeric purities via chiral, non-racemic Lewis acid-promoted, mild, inverse-electron-demand 4+2-cy
