Check Digit Verification of cas no

The CAS Registry Mumber 1612757-25-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,2,7,5 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1612757-25:
(9*1)+(8*6)+(7*1)+(6*2)+(5*7)+(4*5)+(3*7)+(2*2)+(1*5)=161
161 % 10 = 1
So 1612757-25-1 is a valid CAS Registry Number.

Synthesis of novel fluoro analogues of MKC442 as microbicides

Loksha, Yasser M.,Pedersen, Erik B.,Loddo, Roberta,Sanna, Giuseppina,Collu, Gabriella,Giliberti, Gabriele,Colla, Paolo La

, p. 5169 - 5178 (2014/07/08)

Novel analogues of MKC442 (6-benzyl-1-(ethoxymethyl)-5-isopropylpyrimidine- 2,4(1H,3H)-dione) were synthesized by reaction of 6-[(3,5-dimethylphenyl) fluoromethyl]-5-ethyluracil (5) with ethoxymethyl chloride and formaldehyde acetals. The Sonogashira reaction was carried out on the N1-(p-iodobenzyl)oxy] methyl derivative of compound 5 using propagyl alcohol to afford compound 12 (YML220). The latter compound was selected for further studies since it showed the most potent and selective activity in vitro against wild-type HIV-1 and non-nucleoside reverse transcriptase inhibitor-, nucleoside reverse transcriptase inhibitor-, and protease inhibitor-resistant mutants and a wide range of HIV-1 clinical isolates. 12 also showed microbicidal activity in long-term assays with heavily infected MT-4 cells.
