Check Digit Verification of cas no

The CAS Registry Mumber 41495-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,1,4,9 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 41495-45:
(7*4)+(6*1)+(5*4)+(4*9)+(3*5)+(2*4)+(1*5)=118
118 % 10 = 8
So 41495-45-8 is a valid CAS Registry Number.

Catalytic hydrogenation of valeronitrile over Raney nickel. Part 2: Reactivity of intermediates

Besson, M.,Bonnier, J. M.,Djaouadi, D.,Joucla, M.

, p. 13 - 19 (2007/10/02)

Hydrogenation of valeronitrile on a Raney nickel catalyst, gives rise to primary, secondary and tertiary amines, the proportions of which depend on several factors.Synthesis of dipentylimine which is an intermediate in the formation of dipentylamine from valeronitrile was performed.The hydrogenation of this dipentylimine at different hydrogen pressures and in the presence or absence of ammonia, allowed us to explain the modifications of selectivity observed when we varied these two factors during the reduction of valeronitrile.Secondary products formed on the course of the hydrogenation of valeronitrile in the presence of added primary amines (hexylamine or pentylamine) have also been studied.Secondary amines were found consistent with the mechanism proposed and the reversibility of reaction was confirmed.
