Check Digit Verification of cas no

The CAS Registry Mumber 193265-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,2,6 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 193265-35:
(8*1)+(7*9)+(6*3)+(5*2)+(4*6)+(3*5)+(2*3)+(1*5)=149
149 % 10 = 9
So 193265-35-9 is a valid CAS Registry Number.

Preparation of meso-silylporphyrins via nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents

Hayashi, Satoshi,Endo, Taiga,Takanami, Toshikatsu

, p. 1082 - 1098 (2019/07/31)

– In this paper, we developed a technique for the nickel-catalyzed coupling of meso-brominated Ni(II) porphyrins with silylzinc reagents in order to prepare meso-silyl-substituted Ni(II) porphyrins. Porphyrin silylation occurs under mild conditions and ex

Functionalization of 5,15-diphenylporphyrin: Preparation and X-ray crystal structures of meso nitro, bromo, and trimethylsilylethynyl derivatives

Arnold, Dennis P.,Bott, Raymond C.,Eldridge, Helen,Elms, Fiona M.,Smith, Graham,Zojaji, Mike

, p. 495 - 503 (2007/10/03)

Substitutions on 5,15-diphenylporphyrin led to the isolation of mono- and di-bromo and mono- and di-nitro derivatives, which were converted into their respective nickel(II) complexes. Reaction of the bromoporphyrins with iodine/silver nitrite resulted in nitrodebromination as well as conventional nitration. The nickel (II) complex of 5-nitro-10,20-diphenylporphyrin was reduced to the 5-amino derivative. The nickel(II) complexes of the bromoporphyrins were converted into the respective mono- and bis-(trimethylsilylethynyl) species. The crystal structures of 5-nitro-10,20-diphenylporphyrin, 5-bromo-10,20-diphenylporphyrinatonickel(II), and 10,20-diphenyl-5-(trimethylsilylethynyl)porphyrinatonickel(II) were determined.
