114740-45-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 114740-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,4,7,4 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 114740-45:
(8*1)+(7*1)+(6*4)+(5*7)+(4*4)+(3*0)+(2*4)+(1*5)=103
103 % 10 = 3
So 114740-45-3 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
