1292302-47-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1292302-47-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,9,2,3,0 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1292302-47:
(9*1)+(8*2)+(7*9)+(6*2)+(5*3)+(4*0)+(3*2)+(2*4)+(1*7)=136
136 % 10 = 6
So 1292302-47-6 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 (2011/05/09)
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.
