Check Digit Verification of cas no

The CAS Registry Mumber 94191-30-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,1,9 and 1 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94191-30:
(7*9)+(6*4)+(5*1)+(4*9)+(3*1)+(2*3)+(1*0)=137
137 % 10 = 7
So 94191-30-7 is a valid CAS Registry Number.

One-Pot Synthesis of N-Alkylpyrrolidines by 1,3-Dipolar Cycloaddition

Imai, Nobuyuki,Achiwa, Kazuo

, p. 593 - 601 (2007/10/02)

N-Alkylpyrrolidines were obtained by one-pot synthesis through 1,3-dipolar cycloaddition of the N-alkylazomethine ylide intermediates generated from N-(benzylidene)trimethylsilylmethylamine and alkyl halide or tosylate.

1,3-DIPOLAR CYCLOADDITION LEADING TO N-ALKYLPYRROLIDINES

Achiwa, Kazuo,Imai, Nobuyuki,Inaoka, Tetsuya,Sekiya, Minoru

, p. 2878 - 2881 (2007/10/02)

1,3-Dipolar cycloaddition of an intermediary methyleneiminium ylide formed from N-(benzylidene)trimethylsilylmethylamine and alkyl halide to conjugated olefinic dipolarophiles has been found to give N-alkylpyrrolidines.KEYWORDS - N-alkylpyrrolidine; N-unsubstituted pyrrolidine; 1,3-dipolar cycloaddition; N-alkyltrimethylsilylmethyliminium salt; methyleneiminium ylide
