Check Digit Verification of cas no

The CAS Registry Mumber 284688-07-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,4,6,8 and 8 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 284688-07:
(8*2)+(7*8)+(6*4)+(5*6)+(4*8)+(3*8)+(2*0)+(1*7)=189
189 % 10 = 9
So 284688-07-9 is a valid CAS Registry Number.

Syntheses and crystal structures of ferrocenyl derivatives of biphenyl

Lemenovskii,Makarov,Dyadchenko,Bruce,Bruce,Larkin,Averkiev,Starikova,Antipin

, p. 607 - 615 (2007/10/03)

Arylation of ferrocene with substituted biphenyldiazonium tetrafluoroborates afforded 4-bromo-, 4-nitro-, and 4-cyano-4′- ferrocenylbiphenyls. 4-Nitro- and 4-cyano-4′-ferrocenylbiphenyls were studied by X-ray diffraction analysis. In the crystals of 4-nitro-4′- ferrocenylbiphenyl, the molecules are linked via stacking π-π interactions.
