1146805-87-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1146805-87-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,4,6,8,0 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1146805-87:
(9*1)+(8*1)+(7*4)+(6*6)+(5*8)+(4*0)+(3*5)+(2*8)+(1*7)=159
159 % 10 = 9
So 1146805-87-9 is a valid CAS Registry Number.

Synthesis of mixed aryl 2,3-diarylsulphanyl-1,4-naphthoquinones
Singh, W. Marjit,Baruah, Jubaraj B.
experimental part, p. 1433 - 1442 (2009/09/30)
The reaction of 2-arylsulphanyl-1,4-napththoquinone with aromatic thiols and sodium dithionate leads to bis-2,3-(arylsulphanyl)naphthalene-1,4-diols in high yield. Corresponding oxidized products, namely 2,3-diarylsulphanyl-1,4- naphthoquinones, are prepa
