The CAS Registry Mumber 1228539-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,5,3 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1228539-19:
(9*1)+(8*2)+(7*2)+(6*8)+(5*5)+(4*3)+(3*9)+(2*1)+(1*9)=162
162 % 10 = 2
So 1228539-19-2 is a valid CAS Registry Number.

Microwave-assisted synthesis of nitro-substituted tetrahydropyrido azepines

Schultz, Thomas,Turner, Sean C.,Braje, Wilfried M.

experimental part, p. 1339 - 1343 (2010/07/06)

The microwave-assisted condensation of azepan-4-ones with 3,5-dinitro-1-methylpyridin-2-one in the presence of ammonia was found to be a highly efficient method for the synthesis of nitro-substituted tetrahydropyridoazepines. Variation of the substituent at the amino group enables the regioselective synthesis of tetrahydropyrido[3,2-c]azepines and tetrahydropyrido[2,3-d]azepines. Georg Thieme Verlag Stuttgart · New York.
