Check Digit Verification of cas no

The CAS Registry Mumber 143770-57-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,7 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 143770-57:
(8*1)+(7*4)+(6*3)+(5*7)+(4*7)+(3*0)+(2*5)+(1*7)=134
134 % 10 = 4
So 143770-57-4 is a valid CAS Registry Number.

Preparation of Benzonaphthyridines

Nutaitis, Charles F.,Marsh, Stephen R.

, p. 971 - 973 (2007/10/02)

A divergent synthesis of substituted benzonaphthryridines 5a-h is described, which features an intramolecular pyridine cyclization step as the key reaction.The pyridine precursors are conveniently prepared from the pyridinium hydrochloride 2 and the requisite anilines.Cyclization of the non-symmetric substrates 3e and 3f did not proceed with significant regioselectivity.
