Check Digit Verification of cas no

The CAS Registry Mumber 1172999-19-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,2,9,9 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1172999-19:
(9*1)+(8*1)+(7*7)+(6*2)+(5*9)+(4*9)+(3*9)+(2*1)+(1*9)=197
197 % 10 = 7
So 1172999-19-7 is a valid CAS Registry Number.

Salan ligands assembled around chiral bipyrrolidine: Predetermination of chirality around octahedral Ti and Zr centres

Sergeeva, Ekaterina,Kopilov, Jacob,Goldberg, Israel,Kol, Moshe

, p. 3053 - 3055 (2009)

The first synthesis of Salan ligands assembled around the chiral 2,2′-bipyrrolidine backbone is described; as chelation to a metal can only occur via specific faces of the two pyrrolidine nitrogens, these ligands lead to predetermined chirality at metal c
