Check Digit Verification of cas no

The CAS Registry Mumber 269740-01-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,7,4 and 0 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 269740-01:
(8*2)+(7*6)+(6*9)+(5*7)+(4*4)+(3*0)+(2*0)+(1*1)=164
164 % 10 = 4
So 269740-01-4 is a valid CAS Registry Number.

Synthesis and antibacterial studies of a new series of 1,2-bis(1,3,4- oxadiazol-2-yl)ethanes and 1,2-bis(4-amino-1,2,4-triazol-3-yl)ethanes

Holla, B. Shivararna,Gonsalves, Richard,Shenoy, Shalini

, p. 267 - 271 (2007/10/03)

The acylhydrazones 3, obtained by the treatment of succinic acid dihydrazide 2 with furfural, nitrofurfuraldehydediacetate and substituted arylfurfurals, on oxidative cyclization with bromine in acetic acid yielded 1,2-bis(1,3,4-oxadiazol-2-yl)ethanes 4 which are further converted into 1,2- bis(4-amino-1,2,4-triazol-3-yl)ethanes 5 with hydrazine hydrate. The newly synthesised compounds are characterised by analytical, IR, NMR and mass spectral data. Most of the newly synthesised compounds have been found to be active against both Gram positive and Gram negative bacteria at less than 6 μg/mL concentration.
