125145-45-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 125145-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,1,4 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 125145-45:
(8*1)+(7*2)+(6*5)+(5*1)+(4*4)+(3*5)+(2*4)+(1*5)=101
101 % 10 = 1
So 125145-45-1 is a valid CAS Registry Number.

SYNTHESIS OF GALANTHAMINE AND RELATED ALKALOIDS - NEW APPROARCHES. I.

Vlahov, Radoslav,Krikorian, Dikran,Spassov, Grigor,Chinova, Maja,Vlahov, Ioncho,et al.

, p. 3329 - 3346 (2007/10/02)

Modifications of protecting groups and of the oxidative coupling conditions led to pure crystalline intermediates in the synthesis of galanthamine derivatives and gave dienone A in better yields than reported before.The E-configuration of amide 3' in crystalline state has been determined by X-ray diffraction.Streptomyces affinis 6737 reduces A to the optically active (-)-epigalanthamine derivative C, whose absolute configuration was determined by Bijvoet's method.Nematospora corylii CBS 2608 reduces to racemic B.With Ashbya gossypii IFO 1355 a mixture of racemic B and of optically active C is obtained.Some other microbial transformations are described.
