Check Digit Verification of cas no

The CAS Registry Mumber 222295-27-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,2,2,9 and 5 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 222295-27:
(8*2)+(7*2)+(6*2)+(5*2)+(4*9)+(3*5)+(2*2)+(1*7)=114
114 % 10 = 4
So 222295-27-4 is a valid CAS Registry Number.

Synthesis and biological evaluation of 5-arylfuro[2,3-d]pyrimidines as novel dihydrofolate reductase inhibitors

Wahid, Farid,Monneret, Claude,Dauzonne, Daniel

, p. 156 - 164 (2007/10/03)

A series of about fifty novel 5-arylfuro[2,3-d]pyrimidine derivatives were synthesized as potential inhibitors of dihydrofolate reductase (DHFR) arising from different species. Weak enzyme inhibition was observed for most of the compounds, with only a few reaching IC50 values less than 30 μM. With regards to antibacterial and antimalarial potency, only seven compounds showed a modest in vitro activity against some bacteria strains and only three products proved significantly active against P. falciparum.
