144069-04-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 144069-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,0,6 and 9 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144069-04:
(8*1)+(7*4)+(6*4)+(5*0)+(4*6)+(3*9)+(2*0)+(1*4)=115
115 % 10 = 5
So 144069-04-5 is a valid CAS Registry Number.

Enzyme-catalysed Hydrolysis of 3,5-cis-Diacetoxy-4-trans-benzyloxymethylcyclopentene and the Synthesis of Aristeromycin Precursors
LeGrand, Darren M.,Roberts, Stanley M.
, p. 1751 - 1752 (2007/10/02)
The optically active mono-ester 2 was obtained by enzyme-catalysed hydrolysis of the diester 1 and converted into the azide 8 and the amine 13, synthetic precursors of (+)- and (-)-aristeromycin.
