Check Digit Verification of cas no

The CAS Registry Mumber 4559-79-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,5,5 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4559-79:
(6*4)+(5*5)+(4*5)+(3*9)+(2*7)+(1*9)=119
119 % 10 = 9
So 4559-79-9 is a valid CAS Registry Number.

Palladium-promoted 1,4-Cycloamination of 1,3-Dienes to Pyrroles

Baeckvall, Jan-E.,Nystroem, Jan-E.

, p. 59 - 61 (2007/10/02)

1,3-Dienes react with palladium(II) chloride and acetic acid with the formation of 4-acetoxy-alk-2-enyl-palladium complexes (2), which on reaction with primary amines give N-alkylpyrroles.
