185684-95-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 185684-95-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,6,8 and 4 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 185684-95:
(8*1)+(7*8)+(6*5)+(5*6)+(4*8)+(3*4)+(2*9)+(1*5)=191
191 % 10 = 1
So 185684-95-1 is a valid CAS Registry Number.

Transition metals in organic synthesis, part 104. Iron-mediated total synthesis of furoclausine-A

Krahl, Micha P.,Schmidt, Arndt W.,Knoelker, Hans-Joachim

, p. 357 - 370 (2013/08/23)

Using iron-mediated coupling reactions a convergent seven-step synthesis of the furo[3,2-a]carbazole alkaloid furoclausine-A is achieved.

Transition metal complexes in organic synthesis, part 63;1 convergent iron-mediated syntheses of the furo[3,2-a]carbazole alkaloid furostifoline

Knolker,Frohner

, p. 2131 - 2136 (2007/10/03)

Two highly efficient routes to the furo[3,2-a]carbazole alkaloid furostifoline are described. Both syntheses use the iron-mediated arylamine cyclization as the key-step and lead to the natural product in seven and five steps, respectively.
