137265-54-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137265-54-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,2,6 and 5 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 137265-54:
(8*1)+(7*3)+(6*7)+(5*2)+(4*6)+(3*5)+(2*5)+(1*4)=134
134 % 10 = 4
So 137265-54-4 is a valid CAS Registry Number.

Revision of the enantiotoposelective PLE-catalyzed hydrolysis of cis-5-substituted-1,3-diacyloxycyclohexanes
Dumortier, L.,Carda, M.,Eycken, J. Van der,Snatzke, G.,Vandewalle, M.
, p. 789 - 792 (2007/10/02)
Revision of previous work shows that PLE-catalyzed hydrolysis of 1 leads to the (S)-alcohol 5 and not the (R)-alcohol 3.However the homologue 2 gives the (R)-alcohol 4.
