Check Digit Verification of cas no

The CAS Registry Mumber 247586-21-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,5,8 and 6 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 247586-21:
(8*2)+(7*4)+(6*7)+(5*5)+(4*8)+(3*6)+(2*2)+(1*1)=166
166 % 10 = 6
So 247586-21-6 is a valid CAS Registry Number.

On the enantiomers of 2-dimethylamino-3-pentanone, key intermediates in the synthesis of analgesic alkylaminoalkylnaphthalenes

Collina, Simona,Benevelli, Francesca,Vercesi, Dina,Ghislandi, Victor

, p. 2387 - 2397 (2007/10/03)

2-Dimethylamino-3-pentanone 1 is the key intermediate in the synthesis of alkylaminoalkylnaphthalenic analgesics. In this paper the resolution of this compound with L- and D-dibenzoyltartaric acids is described The behavior of the diastereomeric dibenzoyltartrates and of the enantiomers in solution is investigated by NMR spectroscopy, polarimetry and chiral gas- chromatographic analysis.
