Calculate Digit Verification of CAS Registry Number 24043-89:
(7*2)+(6*4)+(5*0)+(4*4)+(3*3)+(2*8)+(1*9)=88
88 % 10 = 8
So 24043-89-8 is a valid CAS Registry Number.

Diastereoselective synthesis of pinacols from aromatic aldehydes using the system pentacarbonyliron-hexamethylphosphoric triamide. Dual reactivity of pentafluorobenzaldehyde

Terent'ev,Vasil'eva,Chakhovskaya,Mysova,Kochetkov

, p. 518 - 521 (2007)

The system Fe(CO)5-HMPA effectively promotes diastereoselective reductive dimerization of aromatic aldehydes to the corresponding pinacols having preferentially or exclusively dl configuration. In the reaction with pentafluorobenzaldehyde, the product structure strongly depends on the presence of traces of moisture in the reaction system. Nauka/Interperiodica 2007.
