Check Digit Verification of cas no

The CAS Registry Mumber 103868-26-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,8,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 103868-26:
(8*1)+(7*0)+(6*3)+(5*8)+(4*6)+(3*8)+(2*2)+(1*6)=124
124 % 10 = 4
So 103868-26-4 is a valid CAS Registry Number.

Cyanothioacetamide and its derivatives in heterocyclic synthesis: A new route for the synthesis of several pyridine and thieno[2,3-b]pyridine derivatives and their biological evaluation

Eldin, Sanaa M.

, p. 674 - 680 (2007/10/03)

Several new pyridine and thieno[2,3-b]pyridine derivatives were synthesized via the reactions of some pyridinethiones, obtained by the action of acetylacetone on some thiocarboxamidocinnamonitriles, with halogenated esters and ketones. Structures were established based on elemental and spectral data. All the synthesized compounds were tested for their biological activity.
