Check Digit Verification of cas no

The CAS Registry Mumber 93969-56-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,9,6 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93969-56:
(7*9)+(6*3)+(5*9)+(4*6)+(3*9)+(2*5)+(1*6)=193
193 % 10 = 3
So 93969-56-3 is a valid CAS Registry Number.

Reduction of Oximes and Aliphatic Nitro Compounds to Imines for Further in situ Reactions: A Novel Synthesis of Pyrroles and Pyrrolin-2-ones

Barton, Derek H. R.,Motherwell, William B.,Simon, Ethan S.,Zard, Samir Z.

, p. 2243 - 2252 (2007/10/02)

Tributhylphosphine-diphenyl disulphide is a self-drying reagent capable of reducing ketoximes and secondary aliphatic nitro compounds to the corresponding imines under strictly anhydrous conditions at room temperature.The imine may be hydrolysed to a ketone, acetylated to give an enamide, reduced to an amine , or captured by hydrogen cyanide to produce an α-amino nitrile.In the case of 1,4-nitro ketones or esters, intramolecular cyclisation leads to pyrroles or pyrrolin-2-ones.Aldoximes and primary nitro compounds are converted into nitriles by the reagent.Hydroxamic acids are reduced to the corresponding amides.
