1304461-02-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1304461-02-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,4,6 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1304461-02:
(9*1)+(8*3)+(7*0)+(6*4)+(5*4)+(4*6)+(3*1)+(2*0)+(1*2)=106
106 % 10 = 6
So 1304461-02-6 is a valid CAS Registry Number.

Facile Cu(OTf)2-catalyzed preparation of 9-tosylaminofluorene derivatives from o-arylated N-tosylbenzaldimines
Yu, Xufen,Lu, Xiyan
, p. 2076 - 2079 (2011)
The 9-tosylaminofluorene derivatives were synthesized conveniently by Cu(OTf)2-catalyzed aza-Friedel-Crafts reaction of o-arylated N-tosylbenzaldimines in high yields. This is an efficient, atom-economic, and green method.
