1271111-84-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1271111-84-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,7,1,1,1 and 1 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1271111-84:
(9*1)+(8*2)+(7*7)+(6*1)+(5*1)+(4*1)+(3*1)+(2*8)+(1*4)=112
112 % 10 = 2
So 1271111-84-2 is a valid CAS Registry Number.

Reactions of azepinones with electrophiles
Dubinina, Galyna G.,Chain, William J.
, p. 939 - 942 (2011/03/21)
Azepinones are available via a one-pot cycloaddition-ring expansion reaction sequence in good yield. The reactions of azepinones with alkyl halides and epoxides were studied. We report herein protocols for the alkylation of azepinones at nitrogen with alk
