Check Digit Verification of cas no

The CAS Registry Mumber 135766-12-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,6 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135766-12:
(8*1)+(7*3)+(6*5)+(5*7)+(4*6)+(3*6)+(2*1)+(1*2)=140
140 % 10 = 0
So 135766-12-0 is a valid CAS Registry Number.

Copper(II), cobalt(II), cobalt(III), and tin(IV) 5,10,15,20-tetraphenyl tetrabenzoporphyrinates: Synthesis and properties

Chizhova,Mal’tseva,Zav’yalov,Mamardashvili, N. Zh.

, p. 683 - 687 (2017)

The complexation reactions of 5,10,15,20-tetraphenyl tetrabenzoporphyrin and the metal exchange reactions of its cadmium(II) complex with copper(II), cobalt(II), and tin(II) acetates and chlorides in a chloroform–methanol mixture and dimethylformamide were studied spectrophotometrically. Corresponding copper(II), cobalt(II), cobalt(II), and tin(IV) porphyrinates were synthesized and identified.

Trans-effect in kinetics of reactions of mixed solvates of Cu(II) acetate with tetraphenyltetrabenzoporphine in organic solvents

Berezin,Toldina

, p. 579 - 583 (2004)

The kinetics of complex formation of tetraphenyltetrabenzoporphine with Cu(II) and Zn(II) acetates is studied in individual and mixed coordinating solvents on the basis of DMSO, DMF, and Py. The substantial increase in CuAc2 reactivity in mixed

Effect of a proton-donating solvent on the complexation of classical and nonclassical porphyrins in a pyridine medium

Berezin,Toldina

, p. 1910 - 1916 (2008/10/08)

The inhibitory effect of proton-donating additives (HAc) on the rate of coordination reaction (1) of tetrabenzoporphine (H2TBP, I), tetraphenyltetrabenzoporphine (H2TPTBP, II), and N-substituted porphyrins III and IV in pyridine was established. The N-H bonding state in compounds I and II and the reactivity of these compounds in reaction (1) were shown to be similar to those of nonclassical porphyrins (H2P), whereas N-substituted porphyrins apparently do not belong to this group. The inhibition of reaction (1) in the case of compounds III and IV is due to the high basicity of the tertiary nitrogen atoms in these molecules.
