Check Digit Verification of cas no

The CAS Registry Mumber 74447-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,4 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 74447-88:
(7*7)+(6*4)+(5*4)+(4*4)+(3*7)+(2*8)+(1*8)=154
154 % 10 = 4
So 74447-88-4 is a valid CAS Registry Number.

SYNTHESIS OF THE BACTERIAL COENZYME METHOXATIN

MacKenzie, A. Roderick,Moody, Christopher J.,Rees, Charles W.

, p. 3259 - 3268 (2007/10/02)

A short total synthesis of the bacterial coenzyme methoxatin (1) (4,5-dihydro-4,5-dioxo-1H-pyrroloquinoline-2,7,9-tricarboxylic acid) is described.The route involves the two step conversion of 4-acetamido-2-benzyloxybenzaldehyde (5b) into methyl 6-acetamido-4-benzyloxyindole-2-carboxylate (7b) (74percent), followed by regioselective annulation of the third ring (55percent), and debenzylation and oxidation with benzoyl t-butyl nitroxide to give the tricyclic quinone triester (13) (methoxatin triester) (83percent).
