Check Digit Verification of cas no

The CAS Registry Mumber 886493-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,6,4,9 and 3 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 886493-87:
(8*8)+(7*8)+(6*6)+(5*4)+(4*9)+(3*3)+(2*8)+(1*7)=244
244 % 10 = 4
So 886493-87-4 is a valid CAS Registry Number.

Simple route to 3-(2-indolyl)-1-propanones via a furan recyclization reaction

Butin, Alexander V.,Smirnov, Sergey K.,Stroganova, Tatyana A.,Bender, Wolfgang,Krapivin, Gennady D.

, p. 474 - 491 (2007/10/03)

A simple route to 1-R-3-(2-indolyl)-1-propanones has been elaborated based on recyclization of 2-(2-aminobenzyl)furan derivatives. Being a modification of the Reissert indole synthesis, our approach employs the furan ring as a source of carbonyl function. This approach is general and allows varying of substituents in aromatic ring as well as in 3-position of indole nucleus.
