548459-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 548459-34-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,4,8,4,5 and 9 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 548459-34:
(8*5)+(7*4)+(6*8)+(5*4)+(4*5)+(3*9)+(2*3)+(1*4)=193
193 % 10 = 3
So 548459-34-3 is a valid CAS Registry Number.

Resolution of 1-aryl-1,2,3,4-tetrahydroisoquinolines via crystallization of O-acetylmandelic amides
Suna, Edgars
, p. 251 - 254 (2007/10/03)
(R)-O-Acetylmandelic acid is an efficient chiral auxiliary for the resolution of racemic 1-aryl-1,2,3,4-tetrahydroisoquinolines 2 and 3 via crystallization of the corresponding diastereomeric amides 5 and 7. Acidic hydrolysis of (R,S)-O-acetylmandelylanil
