Check Digit Verification of cas no
The CAS Registry Mumber 5399-93-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,9 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 5399-93:
(6*5)+(5*3)+(4*9)+(3*9)+(2*9)+(1*3)=129
129 % 10 = 9
So 5399-93-9 is a valid CAS Registry Number.

SYNTHESIS OF 2'-DEOXYRIBONUCLEOSIDES OF ALLOPURINOL BY PHASE-TRANSFER GLYCOSYLATION
Seela, F.,Steker, H.
, p. 5017 - 5018 (2007/10/02)
Regioselective glycosylation of 4-methoxy-1H-pyrazolopyrimidine (6b) with the halogenose 7 was achieved by employing phase-transfer techniques.The N-1 glycosylation product 3a was formed in preponderance.It was converted into the allopurinol β-D-2'-deoxyribonucleoside 2.
