Check Digit Verification of cas no

The CAS Registry Mumber 71504-23-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,5,0 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 71504-23:
(7*7)+(6*1)+(5*5)+(4*0)+(3*4)+(2*2)+(1*3)=99
99 % 10 = 9
So 71504-23-9 is a valid CAS Registry Number.

Synthesis and Properties of Cyclic Keto Alkenylammonium Salts

Jung, Michael E.,Love, Brian E.

, p. 1288 - 1290 (1987)

The cyclic keto alkenylammonium salts (4)-(8) have been prepared by a short, general route and their acidic and electrophilic properties examined.

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.
