Check Digit Verification of cas no

The CAS Registry Mumber 133513-05-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,1 and 3 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 133513-05:
(8*1)+(7*3)+(6*3)+(5*5)+(4*1)+(3*3)+(2*0)+(1*5)=90
90 % 10 = 0
So 133513-05-0 is a valid CAS Registry Number.

Direct Cu(I)-catalysed coupling of a carborane to a meso-tetraphenylporphyrin

Frixa, Christophe,Mahon, Mary F.,Thompson, Andrew S.,Threadgill, Michael D.

, p. 1557 - 1559 (2002)

The copper-catalysed coupling of 1,2-dicarbaclosododecaborane(12) with a meso-iodophenylporphyrinatozinc has been investigated. Optimisation of the reaction conditions gave 5-(4-(1,2-dicarbaclosododecaboran(12)yl)phenyl)-10,15,20-triphenylporphyrin as its

SYNTHESIS OF TETRAPHENYLPORPHINES WITH ACTIVE GROUPS IN THE PHENYL RINGS6. SYNTHESIS OF MONOSUBSTITUTED TETRAPHENYLPORPHINES BY DIAZOTIZATION

Syrbu, S. A.,Semeikin, A. S.,Berezin, B. D.

, p. 1255 - 1257 (2007/10/02)

Monoaminophenyltriphenylporphines are diazotized and then used to produce monohalosubstituted tetraphenylporphines.Isomeric mono(p-hydroxyphenylazo)phenyltriphenylporphines are synthesized by replacing the azo group of diazonium salts of monosubstituted porphines with phenol.
