Check Digit Verification of cas no

The CAS Registry Mumber 1448049-21-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,0,4 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1448049-21:
(9*1)+(8*4)+(7*4)+(6*8)+(5*0)+(4*4)+(3*9)+(2*2)+(1*1)=165
165 % 10 = 5
So 1448049-21-5 is a valid CAS Registry Number.

Synthesis, characterization, and antiviral activity of novel fluorinated isatin derivatives

Abbas, Samir Y.,Farag, Awatef A.,Ammar, Yousry A.,Atrees, Abeer A.,Mohamed, Aly F.,El-Henawy, Ahmed A.

, p. 1725 - 1733 (2014/02/14)

New series of Schiff's bases, hydrazones, thiosemicarbazones, thiazoles, and thiocarbohydrazones of 5-fluoroisatin were synthesized by the reaction of 5-fluoroisatin with primary amines, hydrazine hydrate, and thiocarbohydrazides. Thiosemicarbazones were prepared by reacting hydrazone derivatives with isothiocyanates. Upon treatment of thiosemicarbazone derivatives with chloroacetone, the thiazole derivatives were obtained. Some of the prepared compounds exhibited antiviral activity. Springer-Verlag Wien 2013.
