Check Digit Verification of cas no
The CAS Registry Mumber 689260-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,9,2,6 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 689260-53:
(8*6)+(7*8)+(6*9)+(5*2)+(4*6)+(3*0)+(2*5)+(1*3)=205
205 % 10 = 5
So 689260-53-5 is a valid CAS Registry Number.

Ruthenium-based metathesis catalysts with a N-heterocyclic carbene ligand bearing 2,3,4,5-tetraphenylphenyl moieties (1-TPPh and 1-TPPh*) are developed. The highly active catalyst system has been realized in THF by the combination of 1-TPPh* and CuCl as a phosphine scavenger. The Royal Society of Chemistry 2011.
