Check Digit Verification of cas no

The CAS Registry Mumber 76994-86-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,9 and 4 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 76994-86:
(7*7)+(6*6)+(5*9)+(4*9)+(3*4)+(2*8)+(1*6)=200
200 % 10 = 0
So 76994-86-0 is a valid CAS Registry Number.

The Cyclization of 8-Carboxamido-2'-O-tosyladenosine. A New Preparation of 9-β-D-Arabinofuranosyladenine (ara-A)

Divakar, K. J.,Reese, Colin B.

, p. 1191 - 1193 (1980)

In alkaline solution, 8-carboxamido-2'-O-tosyladenosine (4e; R2 = R3 = H), which may be prepared from adenosine in 7 steps, readily cyclizes to give (5); in neutral or weakly basic solution, it undergoes virtually quantitative conversion into ara-A (1a).
