Check Digit Verification of cas no

The CAS Registry Mumber 1369969-32-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,9,9,6 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1369969-32:
(9*1)+(8*3)+(7*6)+(6*9)+(5*9)+(4*6)+(3*9)+(2*3)+(1*2)=233
233 % 10 = 3
So 1369969-32-3 is a valid CAS Registry Number.

Silver-promoted Friedel-Crafts reaction: Concise total synthesis of (-)-ardeemin, (-)-acetylardeemin and (-)-formylardeemin

Wang,Kong,Du,Song,Zhang,Qin

supporting information, p. 2793 - 2797 (2012/11/13)

Total syntheses of multidrug resistant inhibitors (-)-acetylardeemin 2a, (-)-ardeemin 2b, and (-)-formylardeemin 3 have been achieved within 10 steps starting from bromopyrroloinoline 13. The key step involves direct alkylation of 13 with prenyl tributylstannane 11 to yield 12via a silver-promoted asymmetric Friedel-Crafts reaction. Highly efficient installation of the isoprenyl group allowed excellent overall yield. Moreover, the substrate scope of the asymmetric Friedel-Crafts reaction of 13 was expanded to include a variety of arenes 14 to afford natural product-like library analogues 15.
