Check Digit Verification of cas no

The CAS Registry Mumber 20259-40-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,5 and 9 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20259-40:
(7*2)+(6*0)+(5*2)+(4*5)+(3*9)+(2*4)+(1*0)=79
79 % 10 = 9
So 20259-40-9 is a valid CAS Registry Number.

Aluminium-Carbon Bond Reactivity in Geminal Organodialuminium Compounds

Pasynkiewicz, S.,Dluzniewski, T.,Sonnek, Georg

, p. 1 - 6 (2007/10/02)

The reactions of 1,1-bis(diisobutylaluminium)hexane (1) with diethylamine, N-methylaniline, methanol and m-cresol have been studied.During partial protolysis both the aluminium-i-butyl bond and the aluminium-carbon bond in the aluminium-carbon-aluminium bridge undergo cleavage.The route of protolysis mainly depends on the protolytic agent used.The reaction of (1) with acetone has also been studied.Acetone was reduced to i-butanol with a 95percent yield.The ratio of the i-butyl to hexylidene groups from β-hydride elimination is 2:1.
