Check Digit Verification of cas no

The CAS Registry Mumber 1393891-19-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,8,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1393891-19:
(9*1)+(8*3)+(7*9)+(6*3)+(5*8)+(4*9)+(3*1)+(2*1)+(1*9)=204
204 % 10 = 4
So 1393891-19-4 is a valid CAS Registry Number.

Synthesis and bioactivity evaluation of rhodanine derivatives as potential anti-bacterial agents

, p. 403 - 412 (2012/10/08)

Five series of (Z)-5-(4-(2-oxo-2-phenylethoxy)benzylidene)-2- thioxothiazolidin-4-one derivatives (I-V) were synthesized, characterized, and evaluated for their anti-bacterial activity. Most of the synthesized compounds showed potent inhibition against several Gram-positive bacteria (including multidrug-resistant clinical isolates) with MIC values in the range of 1-32 μg/mL. Compounds IIIi, Vb and Vc presented the most potent activity, showing four-fold more potency than norfloxacin (MIC = 8 μg/mL and 4 μg/mL) and 64-fold more activity than oxacillin (MIC > 64 μg/mL) against MRSA CCARM 3167 and 3506 strains with MIC values of 1 μg/mL, and 64-fold more potency than norfloxacin (MIC > 64 μg/mL) and comparable activity to oxacillin (MIC = 1 μg/mL) against the QRSA CCARM 3505 and 3519 strains. None of the compounds exhibited any activity against the Gram-negative bacteria Escherichia coli 1356 at 64 μg/mL.
