Check Digit Verification of cas no

The CAS Registry Mumber 182256-01-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,2,2,5 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 182256-01:
(8*1)+(7*8)+(6*2)+(5*2)+(4*5)+(3*6)+(2*0)+(1*1)=125
125 % 10 = 5
So 182256-01-5 is a valid CAS Registry Number.

Intramolecular activation of aromatic C-H bonds by tantalum alkylidene groups: Evaluating 'cyclometallation resistant' aryloxide ligation

Lockwood, Mark A.,Clark, Janet R.,Parkin, Bernardeta C.,Rothwell, Ian P.

, p. 1973 - 1974 (1996)

The ligands 2,3,5,6-tetraphenylphenoxide and 3,5-dimethyl-2,6-diphenylphenoxide undergo intramolecular aromatic C-H bond activation by tantalum alkylidene groups at rates 20 and 100 times slower than simple 2,6-diphenylphenoxide.
