1426678-81-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1426678-81-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,6,7 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1426678-81:
(9*1)+(8*4)+(7*2)+(6*6)+(5*6)+(4*7)+(3*8)+(2*8)+(1*1)=190
190 % 10 = 0
So 1426678-81-0 is a valid CAS Registry Number.

Construction of spiro -tetrahydroquinolines via intramolecular dearomatization of quinolines: Free of a preinstalled activation group
Wang, Shou-Guo,Zhang, Wei,You, Shu-Li
, p. 1488 - 1491 (2013/06/27)
A highly efficient synthesis of spiro-tetrahydroquinolines (up to 99% yield) has been realized via cascade hydrogenative dearomatization of quinoline and intramolecular aza-Friedel-Crafts alkylation reaction.
