215670-77-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215670-77-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,6,7 and 0 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 215670-77:
(8*2)+(7*1)+(6*5)+(5*6)+(4*7)+(3*0)+(2*7)+(1*7)=132
132 % 10 = 2
So 215670-77-2 is a valid CAS Registry Number.

Illuminating metal-ion sensors: Benzimidazolesulfonamide metal complexes
Martin, David,Rouffet, Matthieu,Cohen, Seth M.
, p. 10226 - 10228 (2010/12/25)
The synthesis, structure, and solution spectroscopy of several (2-sulfonamidophenyl)benzimidazole metal complexes are reported. These ligands, which have been reported as selective molecular sensors for Zn2+, readily form complexes with Co
