Check Digit Verification of cas no

The CAS Registry Mumber 1253523-06-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,3,5,2 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1253523-06:
(9*1)+(8*2)+(7*5)+(6*3)+(5*5)+(4*2)+(3*3)+(2*0)+(1*6)=126
126 % 10 = 6
So 1253523-06-6 is a valid CAS Registry Number.

One-pot formation of piperidine- and pyrrolidine-substituted pyridinium salts via addition of 5-alkylaminopenta-2,4-dienals to N-acyliminium ions: Application to the synthesis of (±)-nicotine and analogs

Peixoto, Sabrina,Nguyen, Tuan Minh,Crich, David,Delpech, Bernard,Marazano, Christian

supporting information; experimental part, p. 4760 - 4763 (2010/12/25)

Addition of 5-alkylaminopenta-2,4-dienals onto N-acyliminium ions, generated in situ from α-hydroxycarbamates derived from pyrrolidine or piperidine, in the presence of zinc triflate, followed by dehydrative cyclization, allowed the formation of pyridinium salts substituted at their 3-position by a five- or six-membered nitrogen heterocycle. Subsequent N-dealkylation of the pyridinium moiety and deprotection of the secondary amine or reduction of the carbamate function led to (±)-nicotine and analogs.
