Check Digit Verification of cas no

The CAS Registry Mumber 94890-82-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,8,9 and 0 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 94890-82:
(7*9)+(6*4)+(5*8)+(4*9)+(3*0)+(2*8)+(1*2)=181
181 % 10 = 1
So 94890-82-1 is a valid CAS Registry Number.

Electronic structure of group 14 (η4-metallole)tricarbonyliron complexes

Guimon,Pfister-Guillouzo,Dubac,Laporterie,Manuel,Iloughmane

, p. 636 - 641 (2008/10/08)

Some methyl derivatives of metalloles R2XC4H4 (X = C, Si, Ge) and their tricarbonyliron complexes have been prepared in order to study the influence of both the group 14 elements and complexation effects on the electronic structure of the diene ring using photoelectron spectroscopy (UPS, He I, He II). Strong electron donation from iron to the metallole ligand has been demonstrated. This transfer, which is the result of participation of the lowest vacant orbital of the ring (3b1) in the highest occupied orbital (HOMO) of the complex, shows that these compounds have a certain aromatic character.
