138827-41-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138827-41-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,2 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 138827-41:
(8*1)+(7*3)+(6*8)+(5*8)+(4*2)+(3*7)+(2*4)+(1*1)=155
155 % 10 = 5
So 138827-41-5 is a valid CAS Registry Number.

1,5-Hexadiene selective hydroformylation reaction catalyzed with Rh(acac)2/P(OPh)3 and Rh(acac)(CO)(PPh3)/PPh3 complexes

Trzeciak, A.M.,Ziolkowski, J.J.

, p. 107 - 112 (1994)

Hydroformylation of 1,5-hexadiene, catalyzed by the system Rh(acac)2/P(OPh)3 (I), leads to the formation of mono- and dialdehydes, 4-heptenal, 2-Me-3-hexenal and octane-1,8-dial, 2,5-Me2-hexanedial respectively.The yield of dialdehydes increases with temperature and pressure and reaches 100percent at 80 deg C and 10 atm of CO/H2 = 1.The reaction catalyzed by Rh(acac)(CO)(PPh3)/PPh3 (II) system produces, besides dialdehydes, monoaldehydes with a terminal double bond, namely 6-heptenal and 2-Me-5-hexenal.The migration of the double bonds in monoaldehydes dependsmainly on the donor properties of modifying ligands.Phosphine when used as a modifying ligand (II), because of its strong donor properties, restricts isomerization (double bond migration) and diminishes yield of 4-heptenal.In contrast, when less strongly donating ligands such as phosphite are used as modifying ligands (I), independently of its steric properties, 4-heptenal is the main reaction product.Key words: Hydroformylation; Rhodium; Hexadiene; Catalysis
