843654-83-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 843654-83-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,3,6,5 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 843654-83:
(8*8)+(7*4)+(6*3)+(5*6)+(4*5)+(3*4)+(2*8)+(1*3)=191
191 % 10 = 1
So 843654-83-1 is a valid CAS Registry Number.

Catalytic Enantioselective Synthesis of Tetrahydocarbazoles and Exocyclic Pictet-Spengler-Type Reactions

Hansen, Casper L.,Ohm, Ragnhild G.,Olsen, Lasse B.,Ascic, Erhad,Tanner, David,Nielsen, Thomas E.

supporting information, p. 5990 - 5993 (2016/12/09)

A synthetic strategy for the synthesis of chiral tetrahydrocarbazoles (THCAs) has been developed. The strategy relies on two types of 6-exo-trig cyclization of 3-substituted indole substrates. Enantioselective domino Friedel-Crafts-type reactions leading to THCAs can be catalyzed by chiral phosphoric acid derivatives (with up to >99% ee), and the first examples of exocyclic Pictet-Spengler reactions to form THCAs are reported.
