Check Digit Verification of cas no

The CAS Registry Mumber 117174-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,7,1,7 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 117174-27:
(8*1)+(7*1)+(6*7)+(5*1)+(4*7)+(3*4)+(2*2)+(1*7)=113
113 % 10 = 3
So 117174-27-3 is a valid CAS Registry Number.

Efficient Synthesis of 2',3'-Dideoxynucleosides and 2',3'-Dideoxy C-Nucleosides from D-Glucosamine

Jung, Michael E.,Trifunovich, Ivan D.

, p. 2921 - 2924 (2007/10/02)

D-Glucosamine 1 can be easily converted into 2,5-anhydro-6-O-benzoyl-3,4-dideoxygluconic acid 6 which can be taken on to both 2',3'-dideoxynucleosides such as dideoxyuridine (ddU) 4 and 2',3'-dideoxy C-nucleosides such as dideoxyformycin B 5 and dideoxyshowdomycin 20.

A NEW SYNTHESIS OF 2',3'-DIDEOXYNUCLEOSIDES FOR AIDS CHEMOTHERAPY

Farina, Vittorio,Benigni, Daniel A.

, p. 1239 - 1242 (2007/10/02)

Dideoxynucleosides were prepared in high optical purity from L-glutamic acid.The condensation reactions between activated 2,3-dideoxypentofuranoses and silylated purines or pyrimidines afforded separable β/α mixtures of dideoxynucleosides.
