103477-04-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103477-04-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,4,7 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103477-04:
(8*1)+(7*0)+(6*3)+(5*4)+(4*7)+(3*7)+(2*0)+(1*4)=99
99 % 10 = 9
So 103477-04-9 is a valid CAS Registry Number.

Catalyst-free and stereoselective synthesis of N,N-bicyclic pyrazolidinone derivatives

Yang, Desuo,Fan, Mingjin,Zhu, Haiyun,Guo, Yaning,Guo, Jiangtao

, p. 1325 - 1332 (2013)

A catalyst-free and stereoselective cycloaddition of pyrazolidin-3-one- derived azomethine imine to trans-β-nitrostyrene is described, which allows versatile, efficient and highly enantioselective synthesis of N,N-bicyclic pyrazolidinone derivatives. Georg Thieme Verlag Stuttgart, New York.

ARE ANY NON-STEREOSPECIFIC 1,3-DIPOLAR CYCLOADDITIONS KNOWN? A REVISION

Huisgen, Rolf,Weinberger, Rudolf

, p. 5119 - 5122 (1985)

The cycloaddition of 1-benzylidenepyrazolid-3-one betaine to (E)-β-nitrostyrene, which has been claimed to furnish 15-30percent non-stereospecific product, revealed stereospecificity up to 99.92percent in a renewed study; (Z)-β-nitrostyrene stereoisomerizes under the influence of the 1,3-dipole

1,3-DIPOLAR CYCLOADDITION OF PYRAZOLID 3-ONE AZOMETHINIMINES AND E-β-NITROSTYRENE - ELUCIDATION OF THE GENERATION OF SEEMINGLY "NON CISOID" ADDUCTS

Dorn, Helmut

, p. 5123 - 5126 (2007/10/02)

Highly polar 1,3-dipoles like pyrazolid-3-one azomethinimines stereospecifically add polar dipolarophiles.A suggested "non cisoid" adduct of E-β-nitrostyrene is generated by epimerization at C-2, catalysed by Kieselgel 40 MERCK and small amounts of pyrazolid-3-one.
