Check Digit Verification of cas no
The CAS Registry Mumber 846-15-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,4 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 846-15:
(5*8)+(4*4)+(3*6)+(2*1)+(1*5)=81
81 % 10 = 1
So 846-15-1 is a valid CAS Registry Number.

Synthesis of 4-nitrophenyl sulfones and application in the modified Julia olefination
Mirk, Daniela,Grassot, Jean-Marie,Zhu, Jieping
, p. 1255 - 1259 (2006)
4-Nitrophenyl (NP) sulfones have been successfully employed in the modified Julia olefination reaction with carbonyl compounds. The olefination reaction proceeds through a sequence of aldol addition, Smiles rearrangement, and elimination. The sulfones are easily prepared in high yields in a two-step sequence starting from inexpensive commercially available para- fluoronitrobenzenes via nucleophilic aromatic substitution by a mercaptane and subsequent oxidation under standard conditions. The modified Julia reaction between NP sulfones and a wide variety of aromatic aldehydes affords the corresponding styrenes, stilbenes and cinnamate derivatives in yields up to 97% and good stereoselectivities. A mechanistic rationale is advanced to explain the observed results. Georg Thieme Verlag Stuttgart.
