Check Digit Verification of cas no

The CAS Registry Mumber 290301-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,0 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 290301-57:
(8*2)+(7*9)+(6*0)+(5*3)+(4*0)+(3*1)+(2*5)+(1*7)=114
114 % 10 = 4
So 290301-57-4 is a valid CAS Registry Number.

Nitrogen heterocycles by palladium-catalyzed cyclization of amino-tethered vinyl halides and ketone enolates

Sole, Daniel,Diaba, Faiza,Bonjoch, Josep

, p. 5746 - 5749 (2007/10/03)

The scope and limitations of Pd(0)-catalyzed intramolecular coupling of amino-tethered vinyl halides and ketone enolates as a methodology for the synthesis of nitrogen heterocycles have been studied. This reaction constitutes a synthetic procedure to obta
