Check Digit Verification of cas no

The CAS Registry Mumber 1100817-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,0,8,1 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1100817-23:
(9*1)+(8*1)+(7*0)+(6*0)+(5*8)+(4*1)+(3*7)+(2*2)+(1*3)=89
89 % 10 = 9
So 1100817-23-9 is a valid CAS Registry Number.

Synthesis and evaluation of antimicrobial activity of hydrazones derived from 3-oxido-1H-imidazole-4-carbohydrazides

Pieczonka, Adam M.,Strzelczyk, Aleksandra,Sadowska, Beata,Mlostoń, Grzegorz,Sta?czek, Pawe?

, p. 389 - 395 (2013/07/19)

In this work we reported the synthesis and evaluation of in vitro antimicrobial activities of hydrazones 6 obtained from 3-oxido-1H-imidazole-4- carbohydrazides 4. All new compounds were characterized by spectroscopic methods. Hydrazones 6 were tested for their in vitro antimicrobial activity against four Gram-positive and four Gram-negative strains of bacteria as well as one fungal species. Three of the tested compounds appeared to be promising agents against reference strains of Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis. They were also tested against twelve clinical isolates of S. aureus and their cytotoxic effect on murine fibroblasts and HeLa human tumor cell line was determined.
