The CAS Registry Mumber 1249643-23-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,9,6,4 and 3 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1249643-23:
(9*1)+(8*2)+(7*4)+(6*9)+(5*6)+(4*4)+(3*3)+(2*2)+(1*3)=169
169 % 10 = 9

Synthesis of N1 -alkyl-1,4-diazepin-5-ones via Schmidt ring expansion chemistry

Frick, Morin,McAtee, Danielle,McAtee, Jesse,Wysoczynski, Christina,Ray, Partha S.

, p. 17 - 19 (2011)

Reaction of 4-piperidone with alkyl bromides gave the corresponding N-alkyl-4-piperidones, and treatment of these with hydrazoic acid resulted in the Schmidt reaction to give the corresponding N1-alkyl-1,4-diazepin- 5-ones in good overall yield
