Check Digit Verification of cas no

The CAS Registry Mumber 99983-93-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,9,8 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 99983-93:
(7*9)+(6*9)+(5*9)+(4*8)+(3*3)+(2*9)+(1*3)=224
224 % 10 = 4
So 99983-93-4 is a valid CAS Registry Number.

Pyrrolidine Analogues of 2',3'-Dideoxynucleosides: Synthesis via 9-Aminopurines and 1-Aminopyrimidines

Harnden, Michael R.,Jarvest, Richard L.

, p. 2073 - 2080 (2007/10/02)

Analogues of 2',3'-dideoxynucleosides in which the tetrahydrofuran ring is replaced by a pyrrolidine ring linked to the base through an N-N bond have been prepared.The adenine 26, guanine 25 and and hypoxanthine 27 compounds were synthesised via 9-aminopurines.Corresponding derivatives of 5-iodouracil 31, 5-chlorouracil 33 and 5-chlorocytosine 35 were prepared by substitution at the 5-position of hydroxy protected uracil derivatives.Enantiomers, 40a and 40b, of the pyrrolidine analogue of dideoxycytidine were prepared from 1-aminocytosine.The novel N-aminobases 9-aminoadenine 10, 1-aminocytosine 13 and 1-aminothymine 15 are described.
