Check Digit Verification of cas no
The CAS Registry Mumber 461644-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,6,1,6,4 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 461644-53:
(8*4)+(7*6)+(6*1)+(5*6)+(4*4)+(3*4)+(2*5)+(1*3)=151
151 % 10 = 1
So 461644-53-1 is a valid CAS Registry Number.

Stereoselective synthesis of (-)-cytoxazone
Carda, Miguel,Gonzalez, Florenci,Sanchez, Richard,Marco
, p. 1005 - 1010 (2007/10/03)
The stereoselective synthesis of the cytokine modulator (-)-cytoxazone in enantiopure form is described. Key steps of the process are a syn-stereoselective aldol addition of a chiral ketone mediated by chlorodicyclohexylborane, and a Curtius rearrangement
