Check Digit Verification of cas no

The CAS Registry Mumber 107643-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,4 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 107643-79:
(8*1)+(7*0)+(6*7)+(5*6)+(4*4)+(3*3)+(2*7)+(1*9)=128
128 % 10 = 8
So 107643-79-8 is a valid CAS Registry Number.

Synthesis of porphyrins with reactive groups on phenyl rings. 8. Azo dyes on tetraphenylporphyrins

Syrbu,Semeikin,Syrbu

, p. 897 - 901 (1996)

Porphyrins having covalently attached residues of azo dyes on the periphery of the molecule have been synthesized by the diazotization of tetraaminophenylporphyrins and subsequent azo coupling of the diazonium salts with phenol, and with α- and β-naphthols. The possibility of π - π electron interaction of the two chromophoric systems has been studied. 1997 Plenum Publishing Corporation.

SYNTHESIS OF TETRAPHENYLPORPHINS WITH REACTIVE GROUPS IN THE BENZENE RINGS. 3. USE OF DIAZOTATION FOR THE PREPARATION OF SUBSTITUTED TETRAPHENYLPORPHINS

Semeikin, A.S.,Koifman, O.I.,Berezin, B.D.

, p. 397 - 401 (2007/10/02)

Diazotization of tetra(aminophenyl)porphins has been employed to obtain halo- and hydroxy-tetraphenylporphins.Azo-coupling of tetra(diazophenyl)porphins has given isomeric tetraporphins.
