Check Digit Verification of cas no

The CAS Registry Mumber 20326-12-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,3,2 and 6 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 20326-12:
(7*2)+(6*0)+(5*3)+(4*2)+(3*6)+(2*1)+(1*2)=59
59 % 10 = 9
So 20326-12-9 is a valid CAS Registry Number.

Substituted 4 phenyl 1 (3 pyrazolyl alkyl) piperazines. II. Synthesis of 3 pyrazolyl ethylamines

Poetsch,Koppe

, p. 162 - 170 (2007/10/05)

Using the tranquilizer mepiprazol (a pyrazolyl 3 ethylamine derivative) as an example, the paper describes a new synthesis of this class of substances starting from appropriately modified β dicarbonyl compounds, the preparation and chemical behavior of which are investigated. The transferability of this method to further pyrazolyl 3 ethylamine derivatives is demonstrated on the basis of some examples. The important intermediate stage for the mechanism of pyrazole cyclisation to these derivatives is taken to be the corresponding enhydrazinoketone.
