782504-42-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 782504-42-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,2,5,0 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 782504-42:
(8*7)+(7*8)+(6*2)+(5*5)+(4*0)+(3*4)+(2*4)+(1*2)=171
171 % 10 = 1
So 782504-42-1 is a valid CAS Registry Number.

Convenient, benign and scalable synthesis of 2- and 4-substituted benzylpiperidines

Agai, Bela,Proszenyak, Agnes,Tarkanyi, Gabor,Vida, Laszlo,Faigl, Ferenc

, p. 3623 - 3632 (2004)

A short, scalable and environmentally benign synthesis of 2- and 4-substituted benzylpiperidines has been developed. The method is based on the temperature-programmed consecutive deoxygenation and heteroaromatic ring saturation of aryl(pyridin-2-yl)- and aryl(pyridin-4-yl)methanols and aryl(pyridin-4-yl)methanones in the presence of Pd/C catalyst. The crucial roles of the temperature, the acidity and the substrate structure in the change of selectivity have been demonstrated by isolation of several substituted aryl(piperidine)methanols. The carbinols and ketones were prepared from commercially available pyridinecarbaldehydes or 4-cyanopyridine and substituted bromobenzenes via organometallic intermediates.
