Check Digit Verification of cas no

The CAS Registry Mumber 889664-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,9,6,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 889664-75:
(8*8)+(7*8)+(6*9)+(5*6)+(4*6)+(3*4)+(2*7)+(1*5)=259
259 % 10 = 9
So 889664-75-9 is a valid CAS Registry Number.

Synthesis, experimental and theoretical study on the structure of some semicarbazides with potential antibacterial activity

Pitucha, Monika,Karczmarzyk, Zbigniew,Kosikowska, Urszula,Malm, Anna

, p. 505 - 511 (2011/06/28)

A series of 1,4-disubstituted semicarbazide and 4,4'-bis[1-substituted semicarbazide]diphenyl-methane derivatives were synthesized to explore their antibacterial activity. New compounds were characterized by elemental analysis and spectroscopic data. In order to find the tautomeric equilibrium for the molecules energy calculations for each possible tautomeric form of model compound 2, and for the most antibacterially active compound 7 in the investigated series, were calculated for the gas phase at the RHF/SCF/6-31G** level of theory.
