127053-48-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127053-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,5 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127053-48:
(8*1)+(7*2)+(6*7)+(5*0)+(4*5)+(3*3)+(2*4)+(1*8)=109
109 % 10 = 9
So 127053-48-9 is a valid CAS Registry Number.

Exploiting the chemistry of strained rings: Synthesis of indoles via domino reaction of aryl iodides with 2 H-azirines

Candito, David A.,Lautens, Mark

supporting information; experimental part, p. 3312 - 3315 (2010/10/19)

(Equation Presented). The highly strained 2H-azirine ring system has been the source of considerable theoretical and synthetic work. The reaction of these strained heterocycles with transition metals has been documented to give rise to ring opening and subsequent formation of varied heterocycles. An interesting domino reaction is described wherein the strained bicyclic alkene, norbornene, mediates the reaction of 2H-azirines with aryl iodides under palladium catalysis to provide indole or polycyclic dihydroimidazole heterocycles.

Reaction of vinyl triflates of α-keto esters with primary amines: Efficient synthesis of aziridine carboxylates

Tranchant, Marie-José,Dalla, Vincent,Jabin, Ivan,Decroix, Bernard

, p. 8425 - 8432 (2007/10/03)

Vinyl triflates of α-keto esters react smoothly with primary amines to provide aziridine carboxylates in good yields. In all cases, little or no stereoselectivity was observed. A mechanistic study has shown that aziridine carboxylates are strictly formed

Regiospecific reductive cleavage of the C(2)-N bond of aziridines substituted with an electron acceptor mediated by Mg/MeOH
