General Description
The chemical compound "[[(2R,3S,4R,5R)-5-(6-aminopurin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy-hydroxyphosphoryl] 5-[(6S)-2-oxo-1,3,3a,4,6,6a-hexahydrothieno[3,4-d]imidazol-6-yl]pentanoate" is a complex molecule consisting of a nucleotide and a thienoimidazole derivative. The nucleotide portion contains a purine base (6-aminopurin-9-yl) linked to a sugar (3,4-dihydroxyoxolan-2-yl) and a phosphate group (methoxy-hydroxyphosphoryl). The thienoimidazole portion contains a ketone group (2-oxo) and a cyclic structure (hexahydrothieno[3,4-d]imidazol-6-yl) linked to a pentanoate group. [[(2R,3S,4R,5R)-5-(6-aminopurin-9-yl)-3,4-dihydroxyoxolan-2-yl]methoxy-hydroxyphosphoryl] 5-[(6S)-2-oxo-1,3,3a,4,6,6a-hexahydrothieno[3,4-d]imidazol-6-yl]pentanoate likely has important biological functions, possibly serving as a precursor for nucleic acid synthesis or as a modulator of cellular signaling pathways.
Check Digit Verification of cas no
The CAS Registry Mumber 4130-20-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,1,3 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 4130-20:
(6*4)+(5*1)+(4*3)+(3*0)+(2*2)+(1*0)=45
45 % 10 = 5
So 4130-20-5 is a valid CAS Registry Number.
