Check Digit Verification of cas no

The CAS Registry Mumber 1261245-28-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,1,2,4 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1261245-28:
(9*1)+(8*2)+(7*6)+(6*1)+(5*2)+(4*4)+(3*5)+(2*2)+(1*8)=126
126 % 10 = 6
So 1261245-28-6 is a valid CAS Registry Number.

Copper(II) triflate-catalyzed intramolecular hydroamination of homoallylic amino alcohols as an expedient route to trans-2,5-dihydro-1H-pyrroles and 1,2-dihydroquinolines

Rao, Weidong,Kothandaraman, Prasath,Koh, Chii Boon,Chan, Philip Wai Hong

supporting information; experimental part, p. 2521 - 2530 (2011/02/21)

A new efficient synthetic route to trans-2,5-dihydro-1H-pyrroles and 1,2-dihydroquinolines that relies on copper(II) triflate-catalyzed intramolecular hydroamination of homoallylic amino alcohols under mild and operationally straightforward conditions is
