152533-08-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 152533-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,5,3 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 152533-08:
(8*1)+(7*5)+(6*2)+(5*5)+(4*3)+(3*3)+(2*0)+(1*8)=109
109 % 10 = 9
So 152533-08-9 is a valid CAS Registry Number.

α-AMINO KETONES FROM AMINO ACIDS AS PRECURSORS FOR THE KNORR PYRROLE SYNTHESIS
Hamby, James M.,Hodges, John C.
, p. 843 - 850 (2007/10/02)
A useful and versatile modification of the Knorr pyrrole synthesis is described.Key α-amino ketone intermediate for the Knorr condensation were readily prepared from the N-methoxy-N-methylamides of amino acids and condensed with 1,3-dicarbonyl compounds t
