144782-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144782-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,8 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 144782-48:
(8*1)+(7*4)+(6*4)+(5*7)+(4*8)+(3*2)+(2*4)+(1*8)=149
149 % 10 = 9
So 144782-48-9 is a valid CAS Registry Number.

Synthesis of enantiomerically pure acyclic α-sulfinyl ketimines
Garcia Ruano, Jose L.,Lorente, Antonio,Rodriguez Ramos, Jesus H.
, p. 2437 - 2450 (2007/10/03)
Two different methods to obtain enantiomerically pure N-alkyl and N- aryl α-sulfinyl ketimines are reported. Reaction of enantiomerically pure α-sulfinyl ketones (1-6) with benzylamine or p-methoxyaniline, in the presence of molecular sieves (3 A), yields
