Check Digit Verification of cas no

The CAS Registry Mumber 114738-93-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,7,3 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 114738-93:
(8*1)+(7*1)+(6*4)+(5*7)+(4*3)+(3*8)+(2*9)+(1*3)=131
131 % 10 = 1
So 114738-93-1 is a valid CAS Registry Number.

Diastereoselective Syntheses of rac-Slaframine and rac-6-epi-Slaframine

Dartmann, Mechthild,Flitsch, Wilhelm,Krebs, Bernt,Pandl, Klaus,Westfechtel, Alfred

, p. 695 - 704 (2007/10/02)

Indolizidinones 8 have been obtained from thalidomide (5) and cyclopropylphosphonium salts 6 in good yields.Acid-catalyzed rearrangement of 8a gave the isomer 11.A regio- and stereoselective acetoxylation of 8a and 11 was achieved with lead tetraacetate: using standard conditions, acetates 15 and 16 were obtained; in the presence of triethylamine, however, 8a has been transformed into the acetoxy derivative 17. rac-6-epi-Slaframine (4) and rac-slaframine (1) were obtained from acetates 16 and 17 on conventional routes.
