Check Digit Verification of cas no

The CAS Registry Mumber 343-76-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,4 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 343-76:
(5*3)+(4*4)+(3*3)+(2*7)+(1*6)=60
60 % 10 = 0
So 343-76-0 is a valid CAS Registry Number.

Synthesis and antiviral activity of new substituted methyl [2-(arylmethylene-hydrazino)-4-oxo-thiazolidin-5-ylidene]acetates

Saeed, Aamer,Al-Masoudi, Najim A.,Latif, Muhammad

, p. 618 - 625 (2013/09/02)

A series of new methyl [2-(arylmethylene-hydrazono)-4-oxo-thiazolidin-5- ylidene]acetates (5a-o) were synthesized via cyclocondensation of thiosemicarbazones (3a-o) with dimethyl but-2-ynedioate (4) in good yields under solvent-free conditions. The environmentally friendly solvent-free protocol overcomes the limitations associated with the customary protracted solution phase synthesis and afforded the title compounds in a few minutes. Compounds 5b-i and 5h-o were evaluated for their antiviral activity against the replication activity of HIV-1 and HIV-2 in MT-4 using the MTT assay. The same compounds were also evaluated in vitro for their selective antiviral activity against hepatitis C virus (HCV) in the Huh 5-2 replicon system (type 1b, Con1 strain).
