123903-02-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123903-02-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,0 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123903-02:
(8*1)+(7*2)+(6*3)+(5*9)+(4*0)+(3*3)+(2*0)+(1*2)=96
96 % 10 = 6
So 123903-02-6 is a valid CAS Registry Number.

Does Cycloaddition between Pentafulvene and Cyclopentadiene Take Place?

Niggli, Urs,Neuenschwander, Markus

, p. 2199 - 2208 (1990)

Reaction of a 1:1 mixture of cyclopentadiene (CPD) and pentafulvene (1a) at 20 deg C gives a complex mixture.The low-molecular-weight part mainly consists of pure and mixed dimers (ca. 73percent) besides corresponding trimers (ca. 20percent) and some corresponding oligomers according to GC/MS investigations (Fig.1).The 3 predominant 'mixed dimers'between CPD and 1a have been separated, and structures 4-6 (Scheme 3) are assigned according to 400- and 600-MHz 1H-NMR investigations.These results show that HOMO(CPD)-LUMO(fulvene) interactions are important in pentafulvene cycloadditions.Dimer 6 results from cycloaddition followed by -H shifts.
