Check Digit Verification of cas no

The CAS Registry Mumber 1027542-53-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,7,5,4 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1027542-53:
(9*1)+(8*0)+(7*2)+(6*7)+(5*5)+(4*4)+(3*2)+(2*5)+(1*3)=125
125 % 10 = 5
So 1027542-53-5 is a valid CAS Registry Number.

Transition-metal-free synthesis of 3-(1-pyrrolidinyl)quinolines and 3-(1-pyrrolidinyl)quinoline 1-oxides via a one-pot reaction of 3-(1-pyrrolidinyl)crotonates with nitrobenzenes

Bujok, Robert,Cmoch, Piotr,Wróbel, Zbigniew,Wojciechowski, Krzysztof

, p. 2397 - 2402 (2017/03/20)

A carbanion of tert-butyl 3-(1-pyrrolidinyl)crotonate adds to nitrobenzenes to form σH-adducts, which in the presence of pivaloyl chloride and triethylamine are converted into 3-(1-pyrrolidinyl)quinolines or 3-(1-pyrrolidinyl)quinoline 1-oxides depending on the nitrobenzene structure. This is the first methodology in which a quinoline ring is constructed from a substrate bearing a pyrrolidinyl ring. Starting from optically pure enamines, the method allows synthesis of the corresponding chiral products without racemisation.
