Check Digit Verification of cas no

The CAS Registry Mumber 1256575-18-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,6,5,7 and 5 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1256575-18:
(9*1)+(8*2)+(7*5)+(6*6)+(5*5)+(4*7)+(3*5)+(2*1)+(1*8)=174
174 % 10 = 4
So 1256575-18-4 is a valid CAS Registry Number.

Synthesis and biological activity of novel 2,5-disubstituted-l,3,4- oxadiazoles

Shailaja,Anitha,Manjula,Rao, B. Vittal

experimental part, p. 1088 - 1097 (2010/10/21)

A new and previously unreported molecular framework of 1,3,4-oxadiazoles incorporating halo pyridines has been synthesised. The derivatives are synthesised starting from substituted pyridinyloxy benzaldehydes, by converting them in to corresponding arylidene hydrazides followed by chloramine-T oxidation to the title compounds. The 2,5-disubstituted 1,3,4- oxadiazole derivatives are tested for antimicrobial activity. Many compounds showed high degree of activity against Staphylococus aureus and Escherichia coli bacteria at 250 μg/mL concentration.
