Check Digit Verification of cas no

The CAS Registry Mumber 89959-09-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,9,5 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 89959-09:
(7*8)+(6*9)+(5*9)+(4*5)+(3*9)+(2*0)+(1*9)=211
211 % 10 = 1
So 89959-09-1 is a valid CAS Registry Number.

, (2020)

A series of titanium (Ti) compounds bearing 2,6-bis(o-hydroxyalkyl)pyridine ligands were synthesized and investigated as catalysts for the ring-opening polymerization of ε-caprolactone (CL) and L-lactide (LA). The Ti complexes with electron-withdrawing gr

A Model for the Active Sites of Oxo-Transfer Molybdoenzymes: Synthesis, Structure, and Properties

Berg, Jeremy M.,Holm, R. H.

, p. 917 - 925 (2007/10/02)

Development of models for the active sites of oxo-transfer molybdoenzymes has been initiated.Suitable models should be capable of oxygen atom transfer to or from the substrate, approach the native coordination unit, and be inert to formation of μ-oxo Mo(V
