Check Digit Verification of cas no
The CAS Registry Mumber 40459-97-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,4,5 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40459-97:
(7*4)+(6*0)+(5*4)+(4*5)+(3*9)+(2*9)+(1*7)=120
120 % 10 = 0
So 40459-97-0 is a valid CAS Registry Number.

A regioselective synthesis of 4-methyl-1-pyrindan-5-one
Reimann,Poschl
, p. 589 - 592 (2007/10/02)
The enamine 7 reacts with crotonic aldehyde in the presence of p-toluenesulphonic acid via the intermediate 8 to yield regioselectively the unknown title compound 9. In alkaline medium, 9 is also formed from 7 and acetylacetaldehyde dimethyl acetal as well as small amounts of 11 and 12; under acidic conditions, however, mixtures of the regioisomers 9/9a are obtained in poor yield. 9a can be separated by fractional crystallisation of the hydrochlorides. Corresponding to 7 the homologous enamine 13 and acetylacetaldehyde acetal by alkaline catalysis gives the 4-methyltetrahydroquinolinone 1, respectively. Improved experimental details for an efficient preparation of the starting compounds 3 and 4 are given.
