Check Digit Verification of cas no

The CAS Registry Mumber 1301726-20-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,7,2 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1301726-20:
(9*1)+(8*3)+(7*0)+(6*1)+(5*7)+(4*2)+(3*6)+(2*2)+(1*0)=104
104 % 10 = 4
So 1301726-20-4 is a valid CAS Registry Number.

Novel 5-(N -alkylaminouracil) acyclic nucleosides

Boncel, Sawomir,Gondela, Andrzej,McZka, MacIej,Tuszkiewicz-Kuznik, Magdalena,Grec, Przemysaw,Hefczyc, Barbara,Walczak, Krzysztof

experimental part, p. 603 - 610 (2011/04/12)

Protocols for the two-step syntheses of new 5-(N-hydroxyalkyl- and 5-N-benzylamino)uracil acyclic nucleosides bearing various functional groups (alkoxy/hydroxy and cyano/ester) are presented. Two groups of the title compounds were synthesised via aminolysis of 5-bromouracil and, subsequently, either coupling with an alkylating agent (2-chloromethoxyethyl acetate), or Michael-type addition to acrylonitrile/methyl acrylate. The reverse sequences for both syntheses were also studied. The target molecules were designed as non-nucleoside reverse transcriptase inhibitors (NNRTI) and are analogues of 1-(hydroxyethoxymethyl)-6-thiophenylthymine (HEPT) and 3-benzyl-1- cyanomethyluracils. The obtained compounds will be used in screening tests for anti-HIV-1 activity. Georg Thieme Verlag Stuttgart New York.
