Check Digit Verification of cas no

The CAS Registry Mumber 224946-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,9,4 and 6 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 224946-94:
(8*2)+(7*2)+(6*4)+(5*9)+(4*4)+(3*6)+(2*9)+(1*4)=155
155 % 10 = 5
So 224946-94-5 is a valid CAS Registry Number.

Synthesis of a novel C-nucleoside, 2-amino-7-(2-deoxy-β-D-erythro- pentofuranosyl)-3H,5H-pyrrolo-[3,2-d]pyrimidin-4one (2'-deoxy-9- deazaguanosine)

, p. 363 - 376 (2007/10/03)

A synthesis of the C-nucleoside, 2-amino-7-(2-deoxy-β-D- erythropentofuranosyl)-3H,5H-pyrrolo[3,2-d]pyrimidin-4-one (9-deaza-2'- deoxyguanosine) was achieved starting from 2-amino-6-methyl-3H-pyrimidin-4- one (5) and methyl 2-deoxy-3,5-di-O-(p-nitrobenzoyl)-D-erythro-pento- furanoside (11). The anomeric configuration of the C-nucleoside was established by 1H NMR, NOEDS and ROESY. This C-nucleoside did not inhibit the growth of T-cell lymphoma cells.
