Check Digit Verification of cas no

The CAS Registry Mumber 221391-06-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,3,9 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 221391-06:
(8*2)+(7*2)+(6*1)+(5*3)+(4*9)+(3*1)+(2*0)+(1*6)=96
96 % 10 = 6
So 221391-06-6 is a valid CAS Registry Number.

Mono- and zerovalent manganese alkyl complexes supported by the α,α′-diiminato pyridine ligand: Alkyl stabilization at the expense of catalytic performance

Reardon, Damien,Aharonian, Ghazar,Gambarotta, Sandro,Yap, Glenn P.A.

, p. 786 - 788 (2008/10/08)

The mono- and zerovalent manganese alkyl complexes supported by the α,α′-diiminato pyridine ligand were analyzed. The reactivity pattern provides both activation of the vanadium metal and a two electron reduction pathway towards rare monovalent vanadium alkyls. The coordination geometry of manganese was identical to that of the Fe and Co supercatalysts with the same distorted square pyramidal arrangement.
