3328-28-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3328-28-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,2 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3328-28:
(6*3)+(5*3)+(4*2)+(3*8)+(2*2)+(1*8)=77
77 % 10 = 7
So 3328-28-7 is a valid CAS Registry Number.

Novel synthesis of 3-carboxamidolactam derivatives via palladium-catalysed aminocarbonylation

Kollár, László,Takács, Attila

, p. 6116 - 6128 (2018/09/12)

Aminocarbonylation of alkenyl and (hetero)aryl iodides using medium-sized 3-aminolactams as N-nucleophiles was carried out in the presence of in situ palladium(0) catalysts. While the iodoalkenes were converted to the corresponding carboxamide under mild

Aminothiazole derivative. I. A convenient synthesis of monocyclic and condensed 5-aminothiazole derivatives

Uchikawa,Fukatsu,Aono

, p. 877 - 887 (2007/10/02)

Treatment of diamides derived from α-amino acids with phosphorus pentasulfide or Lawesson's reagent was shown to provide a convenient method to prepare 5-aminothiazoles. By this method, in addition to monocyclic 5-aminothiazoles 19, novel bicyclic 5-aminothiazole derivatives such as 4,5,6,7-tetrahydrothiazolo[5,4-b]pyridines II, 5,6,7,8-tetrahydro-4H-thiazolo[5,4-b]azepines 7, 4,5,6,7,8,9-hexahydrothiazolo[5,4-b]azocine 16 and related compounds were prepared in moderate to good yields from simple diamides, suggesting the wide versatility of the method.
