Check Digit Verification of cas no

The CAS Registry Mumber 130657-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,5 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130657-41:
(8*1)+(7*3)+(6*0)+(5*6)+(4*5)+(3*7)+(2*4)+(1*1)=109
109 % 10 = 9
So 130657-41-9 is a valid CAS Registry Number.

SYNTHESIS OF BENZOPHENANTHRIDINES FROM 2-AMINO-6,7-DIMETHOXY-3-(3,4-DIMETHOXYPHENYL)-1,4-NAPHTHOQUINONE

Gogilashvili, T. I.,Kurkovskaya, L. N.,Akhvlediani, R. N.,Suvorov, N. N.

, p. 992 - 996 (2007/10/02)

Previously unknown benzophenanthridines with methoxyl substituents in rings A and D were synthesized from 2-amino-6,7-dimethoxy-3-(3,4-dimethoxyphenyl)-1,4-naphthoquinone by N-acylation, reductive acylation, and Bischler-Napieralskii cyclization.The products are of interest in relation to their structural affinity to the highly active antileukemia benzophenanthridine alkaloids.The optimum conditions for the production of 7,12-diacetoxy-5-methyl-2,3,9,10-tetramethoxybenzophenanthridine with high yields were determined.Its hydrolysis by water in boiling dimethyl formamide led to the product from deacetylation at position 7.
