Check Digit Verification of cas no

The CAS Registry Mumber 67902-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,0 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 67902-40:
(7*6)+(6*7)+(5*9)+(4*0)+(3*2)+(2*4)+(1*0)=143
143 % 10 = 3
So 67902-40-3 is a valid CAS Registry Number.

Synthesis and substitution reactions of N-protected 2-(phenylselenonylmethyl)pyrrolidines

Cooper, Matthew A.,David Ward

, p. 181 - 187 (2007/10/03)

Alkyl phenyl selenides derived from the benzeneselenenyl chloride induced cyclization of N-protected pent-4-enylamines can be converted in good yield into the corresponding 2-hydroxymethyl- or 2-alkoxymethyl-substituted pyrrolidines by oxidation to the corresponding selenone, followed by reaction with water (or hydroxide) or with the corresponding alcohol. Details of the reactions and possible mechanisms for the substitution are discussed.

Cyclofunctionalization of Olefinic Urethanes Using Benzeneselenenyl Chloride in the Presence of Silica Gel: A General Route to Nitrogen Heterocycles

Clive, D. L. J.,Farina, Vittorio,Singh, Alok,Wong, Chi Kwong,Kiel, William, A.,Menchen, Steven M.

, p. 2120 - 2126 (2007/10/02)

Ethyl urethanes derived from Δ4 or Δ5 olefinic amines undergo cyclofunctionalization to afford pyrrolidines and piperidines, respectively, when treated with benzeneselenenyl chloride.The reaction is an efficient one when carried out in the presence of silica gel, yields generally being above 80percent for the examples studied.
