220529-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 220529-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,0,5,2 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 220529-99:
(8*2)+(7*2)+(6*0)+(5*5)+(4*2)+(3*9)+(2*9)+(1*9)=117
117 % 10 = 7
So 220529-99-7 is a valid CAS Registry Number.

Synthesis of meso-β doubly linked porphyrin tapes

, p. 1096 - 1097 (2007/10/03)
The oxidation of 5,15-bis(3,5-di-tert-butylphenyl) Ni(II)-porphyrin 1b with Sc(OTf)3 and DDQ led to production of meso-β doubly linked Ni(II)-porphyrin tapes that have large π-electronic communications over the arrays.
