193689-47-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 193689-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,6,8 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 193689-47:
(8*1)+(7*9)+(6*3)+(5*6)+(4*8)+(3*9)+(2*4)+(1*7)=193
193 % 10 = 3
So 193689-47-3 is a valid CAS Registry Number.

Use of the triflamide group for friedel-crafts acylation of N-(β-phenethyl)amino acids to 3-benzazepine derivatives
Kawase, Masami
, p. 1121 - 1129 (2007/10/03)
Triflamides of N-(β-phenethyl)amino acids (1) were treated with P2O5 under the Friedel-Crafts acylation conditions to give the 3-benzazepines in good yields. N-(β-Phenethyl)-N-triflylvaline (1f) and phenylglycine (1g) were efficientl
