1338559-85-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1338559-85-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,8,5,5 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1338559-85:
(9*1)+(8*3)+(7*3)+(6*8)+(5*5)+(4*5)+(3*9)+(2*8)+(1*5)=195
195 % 10 = 5
So 1338559-85-5 is a valid CAS Registry Number.

Synthesis of 14-aryl-14H-dibenzo[a,j]xanthene derivatives using Cu(CH 3CN)4PF6 as catalyst
Soleimani, Ebrahim,Zainali, Mohsen,Lotfi, Shahram
, p. 573 - 576 (2011)
A simple and expedient method for the synthesis of a series of 14-aryl-14H-dibenzo[a.j]xanthenes and bis (14-aryl-14H-dibenzo[a.j]xanthenes) is described through a one-pot condensation of β-naphthol with aryl aldehydes catalyzed by Cu(CH3CN)su
