Check Digit Verification of cas no

The CAS Registry Mumber 20459-96-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,5 and 9 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 20459-96:
(7*2)+(6*0)+(5*4)+(4*5)+(3*9)+(2*9)+(1*6)=105
105 % 10 = 5
So 20459-96-5 is a valid CAS Registry Number.

DIENCARBONSAEUREN AUS 1,3-DIENEN UND CO2 DURCH C-C-VERKNUEPFUNG AN NICKEL(0)

Hoberg, H.,Schaefer, D.,Oster, B. W.

, p. 313 - 320 (1984)

(Lig)Ni0 systems react with 1,3-dienes in the presence of CO2 to give nickela carboxylates.The influence of ligands and temperature on the regioselectivity of the C-C bond formation is elucidated.In some cases the nickela carboxylates undergo reductive elimination under the influence of maleic anhydride, and the coupled diene/CO2 moiety rearranges to give the diene carboxylic acid.A possible reaction sequence is discussed.
