57606-45-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57606-45-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,0 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 57606-45:
(7*5)+(6*7)+(5*6)+(4*0)+(3*6)+(2*4)+(1*5)=138
138 % 10 = 8
So 57606-45-8 is a valid CAS Registry Number.

Reaction of intracomplex salts of α-amino acids with porphyrins: Effect of the nature of porphyrin

Mamardashvili,Berezin

, p. 439 - 442 (2008/10/08)

The kinetics of coordination of porphyrins of different structure with intracomplex copper salts of α-amino acids (glycine, α-alanine, valine) in DMSO has been studied. N-Methyl-5,10,15,20-tetraphenylporphine, with a planar structure disturbed by the introduction of the methyl group into the coordination center, and 2,3,7,8,12,13,17,18-octaphenyltetraazaporphyrin, with a more rigid aromatic system than in porphyrins, react with the α-amino acid complexes of copper(II) faster than 5,10,15,20-tetraphenylporphine. The salt structure has the most dramatic effect on N-methyl-5,10,15,20- tetraphenylporphine coordination. Steric factors are less important when an increase in the ability of the macrocycle to complex formation is ensured by the electron component of the macrocyclic effect.
