Check Digit Verification of cas no

The CAS Registry Mumber 132178-51-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,1,7 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 132178-51:
(8*1)+(7*3)+(6*2)+(5*1)+(4*7)+(3*8)+(2*5)+(1*1)=109
109 % 10 = 9
So 132178-51-9 is a valid CAS Registry Number.

Regiospecific and Highly Stereoselective Electrophilic Addition to Furanoid Glycals: Synthesis of Phosphonate Nucleotide Analogues with Potent Activity against HIV

Kim, Choung Un,Luh, Bing Y.,Martin, John C.

, p. 2642 - 2647 (1991)

Regiospecific and highly stereoselective electrophilic addition to furanoid glycals has been used as a key step in the synthesis of phosphonate isosteres of nucleoside monophosphates.Using this methodology, phosphonate analogues of 1 (ddA), 4 (d4T), and 5 (d4A) monophosphates have been prepared.Present studies have also led to the development of a scheme for the synthesis of the phosphonate isostere of adenosine monophosphate.Despite the acetal structure, phosphonate derivatives 27 and 28 were substantially more acid stable than the corresponding nucleosides 1 and 5 with respect to glycosidic bond cleavage.The phosphonates 22 and 27 exhibited a potent antiretroviral activity comparable to that of 4 (d4T).
