Check Digit Verification of cas no

The CAS Registry Mumber 74185-91-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,1,8 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74185-91:
(7*7)+(6*4)+(5*1)+(4*8)+(3*5)+(2*9)+(1*1)=144
144 % 10 = 4
So 74185-91-4 is a valid CAS Registry Number.

Lanthanide- and DMSO-Induced Ring Opening of 2-Iminooxetanes: Synthesis of β-Lactams and β-Keto Amides

Barbaro, Gaetano,Battaglia, Arturo,Giorgianni, Patrizia

, p. 1020 - 1025 (2007/10/02)

2-Iminooxetanes (1), generated by lanthanide-catalyzed heterocycloaddition of aldehydes to ketene imines, are versatile synthons for β-lactams (2) and for β-keto amides (3).Conversion of 1 into 2 and 3 can be accomplished by either lanthanide-induced or o

2-IMINOXETANES FROM KETENIMINE-ALDEHYDE CYCLOADDITIONS. PART 1: SYNTHESIS AND CONTROLLED RING OPENING OF 2-N-p-TOLYLIMINO-3,3-DIMETHYL-4-PHENYLOXETANE

Barbaro, Gaetano,Battaglia, Arturo,Giorgianni, Patrizia

, p. 2995 - 2998 (2007/10/02)

Regiospecific cycloaddition of benzaldehyde to dimethylketene - N-p-tolylimine, catalyzed by lanthanide shift reagents, afforded the corresponding 2-iminoxetane.Controlled ring opening showed the oxetane to be a versatile building block for the synthesis of the corresponding acyclic -aminoalcohol, β-keto and β-hydroxyamide.In addition isomerization produced the corresponding 2-azetidinone (β-lactam).
