154138-46-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154138-46-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,1,3 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 154138-46:
(8*1)+(7*5)+(6*4)+(5*1)+(4*3)+(3*8)+(2*4)+(1*6)=122
122 % 10 = 2
So 154138-46-2 is a valid CAS Registry Number.

Efficient synthesis of 2,3,4,5-tetrahydro-1H-3-benzazepines by intramolecular Heck reaction
Tietze,Schimpf
, p. 876 - 880 (2007/10/02)
A new facile method for the synthesis of the pharmacologically interesting 3-benzazepine skeleton is described. The easily available iodinated benzene derivative 3 is alkylated with allyl halides 4a-c to afford compounds 5a-c. Pd-catalyzed Heck-type cycli
