105259-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105259-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,2,5 and 9 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 105259-46:
(8*1)+(7*0)+(6*5)+(5*2)+(4*5)+(3*9)+(2*4)+(1*6)=109
109 % 10 = 9
So 105259-46-9 is a valid CAS Registry Number.

Green synthesis of thiophenyl-1,4-naphthoquinones
Kanodia, Saraswati,Thapliyal, Prakash Chander
, p. 833 - 836 (2012/10/29)
Reaction of 1,4-naphthoquinones adsorbed on neutral alumina to thiophenols in ambient conditions gave respective mono thiophenyl 1,4-naphthoquinones regioselectively in quantitative yield. The solvent free synthesis and quantitative conversion makes the process practical method.
