Check Digit Verification of cas no

The CAS Registry Mumber 189124-63-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,2 and 4 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189124-63:
(8*1)+(7*8)+(6*9)+(5*1)+(4*2)+(3*4)+(2*6)+(1*3)=158
158 % 10 = 8
So 189124-63-8 is a valid CAS Registry Number.

Synthesis of novel porphyrin chromophores from nitroarenes: Further applications of the Barton-Zard pyrrole condensation

Lash, Timothy D.,Wijesinghe, Chaminda,Osuma, Augustine T.,Patel, Jyoti R.

, p. 2031 - 2034 (1997)

Porphyrins with fused nitronaphthalene and benzothiadiazole subunits have been synthesized by the '2 + 2' and '3 + 1' methodologies; the key pyrrolic intermediates were prepared by the base catalyzed condensation of dinitronaphthalenes or 4-nitro-2,1,3-benzothiadiazole with isocyanoacetates.
