Originator
Sotal,G. Ramon
Manufacturing Process
From ethyl 1-methylpiperidine-3-carboxylate (which was prepared by
hydrogenation of ethyl nicotinate with Ni-catalyst and then by methylation by
action dimethyl sulfate) and 2-thienyl magnesium bromide was synthesized
1,1-di(thiophen-2-yl)-2-(3'-N-methylpiperidine), 3-(di-2-thienylmethylene)-1-
methylpiperidine was obtained by dehydration of 1,1-di(thiophen-2-yl)-2-(3'-
N-methylpiperidine) by action of base.

Check Digit Verification of cas no
The CAS Registry Mumber 5169-78-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,6 and 9 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 5169-78:
(6*5)+(5*1)+(4*6)+(3*9)+(2*7)+(1*8)=108
108 % 10 = 8
So 5169-78-8 is a valid CAS Registry Number.
