Check Digit Verification of cas no

The CAS Registry Mumber 85899-55-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,9 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 85899-55:
(7*8)+(6*5)+(5*8)+(4*9)+(3*9)+(2*5)+(1*5)=204
204 % 10 = 4
So 85899-55-4 is a valid CAS Registry Number.

RADIATION CHEMISTRY OF DNA COMPONENTS. FORMATION OF THE 8,5'-CYCLO-2',5'-DIDEOXYGUANOSINE BY GAMMA IRRADIATION OF DEAERATED AQUEOUS SOLUTIONS OF 2'-DEOXYGUANOSINE AND ITS 5'-MONOPHOSPHATE ESTER

Berger, M.,Cadet, J.

, p. 435 - 438 (1983)

8,5'-cyclo-2',5'-dideoxyguanosine was shown to be produced by gamma irradiation of deaerated aqueous solutions of 2'-deoxyguanosine and 2'-deoxyguanosine-5'-monophosphate, subsequent to initial hydrogen abstraction at the osidic carbon C(4').Structure assignment was made on the basis of UV, 1H and 13C NMR, mass spectrometry analyses, and confirmed by an independent synthesis.
