143879-47-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143879-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143879-47:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*9)+(2*4)+(1*7)=164
164 % 10 = 4
So 143879-47-4 is a valid CAS Registry Number.

Synthesis of Indoles via Amidoselenation
Izumi, Taeko,Sugano, Miwa,Konno, Touru
, p. 899 - 904 (2007/10/02)
The reaction of 2-styrylacetanilides (2) with N-phenylselenosuccinimide affords 1-N-acetyl-2-phenyl-3-phenylselenoindoles (3) and 1-N-acetyl-2-phenylindoles (4).The reaction of 2-vinylacetanilides (5) with phenylselenenyl bromide proceeds to form indoles via an intramolecular amidoselenation.
