Check Digit Verification of cas no

The CAS Registry Mumber 1297961-57-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,7,9,6 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1297961-57:
(9*1)+(8*2)+(7*9)+(6*7)+(5*9)+(4*6)+(3*1)+(2*5)+(1*7)=219
219 % 10 = 9
So 1297961-57-9 is a valid CAS Registry Number.

Microwave-assisted aminocarbonylation of ynamides by using catalytic [Fe3(CO)12] at low pressures of carbon monoxide

Pizzetti, Marianna,Russo, Adele,Petricci, Elena

, p. 4523 - 4528 (2011/06/20)

The microwave-assisted aminocarbonylation of ynamides at low pressures of CO is reported. A new class of (E)-acrylamides that are potentially suitable for several applications has been regioselectively synthesized after microwave irradiation for only 20 min by using eco-friendly [Fe3(CO) 12] as the catalyst precursor and triethylamine as the ligand. This transformation is atom economic as all reactants are used in stoichiometric quantities. Furthermore, the transformation is efficiently applied to the alkoxycarbonylation of alkynes as well. Moreover, running these reactions under microwave irradiation allows the simplification of the reaction conditions with remarkable reductions in time, temperature and gas pressure.
