Check Digit Verification of cas no

The CAS Registry Mumber 117675-32-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,6,7 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 117675-32:
(8*1)+(7*1)+(6*7)+(5*6)+(4*7)+(3*5)+(2*3)+(1*2)=138
138 % 10 = 8
So 117675-32-8 is a valid CAS Registry Number.

PHTHALOCYANINES AND RELATED COMPOUNDS. XXXV. SYNTHESIS AND COORDINATION CHEMISTRY OF SUBSTITUTED MANGANESE PHTHALOCYANINES

Dolotova, O. V.,Bundina, N. I.,Derkacheva, V. M.,Negrimovskii, V. M.,Minin, V. V.,et al.

, p. 1699 - 1708 (2007/10/02)

Derivatives of manganese phthalocyanine substituted on the periphery of the macrocycle fit into a series of the following coordination forms: PcMnIIIX, L->PcMnIII-O-MnIIIPcII, PcMnIILn (X, aniono ligand; L, base; n=1,2), with stability against oxidation-reduction and protolytic transformations essentially dependent on the nature of the substituents.The PcMnIILn forms may exist as electronic isomers, Pc+*MnILn and Pc-MnIIILn, due to close packing on the energy scale of d orbitals of the manganese atom and ? orbitals of the macro ligand.
