855749-12-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 855749-12-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,7,4 and 9 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 855749-12:
(8*8)+(7*5)+(6*5)+(5*7)+(4*4)+(3*9)+(2*1)+(1*2)=211
211 % 10 = 1
So 855749-12-1 is a valid CAS Registry Number.

Synthesis of carbazoles by dehydro Diels-Alder reactions of ynamides

Martínez-Esperón, M. Fernanda,Rodríguez, David,Castedo, Luis,Saá, Carlos

, p. 3674 - 3686 (2008/09/19)

A new approach to carbazoles and benzannulated carbazoles by means of intramolecular dehydro Diels-Alder of ynamides is reported. N-(o-Ethynyl)aryl ynamides and N-(o-ethynyl) arylynamides were prepared in a few steps starting from o-iodoaniline. Thermal c

Coupling and cycloaddition of ynamides: Homo- and Negishi coupling of tosylynamides and intramolecular [4 + 2] cycloaddition of N-(o-ethynyl)phenyl ynamides and arylynamides

Martínez-Esperón, María Fernanda,Rodríguez, David,Castedo, Luis,Saá, Carlos

, p. 3843 - 3855 (2007/10/03)

N,N′-aryl- and N,N′-alkyl-buta-1,3-diyne-1,4-ditosylamides have been synthesized for the first time, in good to excellent yields, by copper-catalyzed dimerization of the corresponding N-aryl or N-alkyl tosylynamides. Negishi coupling of N-ethynylzinc tosy

Synthesis of carbazoles from ynamides by intramolecular dehydro Diels-Alder reactions
