139437-22-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139437-22-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,3 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 139437-22:
(8*1)+(7*3)+(6*9)+(5*4)+(4*3)+(3*7)+(2*2)+(1*2)=142
142 % 10 = 2
So 139437-22-2 is a valid CAS Registry Number.

Synthesis of novel tetrahydrobenzazepinones
Busacca, Carl A.,Johnson, Robert E.
, p. 165 - 168 (2007/10/02)
The synthesis of novel tetrahydrobenzazepinones 1, 2, and 3 is described, as well as an improved synthesis of 4. The palladium catalyzed arylation approach to 1, 2, and 4 allows facile entry to benzazepinones lacking electron donating substituents on the
