1601-94-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1601-94-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,0 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1601-94:
(6*1)+(5*6)+(4*0)+(3*1)+(2*9)+(1*4)=61
61 % 10 = 1
So 1601-94-1 is a valid CAS Registry Number.

17O NMR Spectra of Tertiary Alcohols, Ethers, Sulfoxides and Sulfones in the Cyclohexyl and 5-Substituted 1,3-Dioxanyl Series and Related Compounds

Manoharan, Muthiah,Eliel, Ernest L.

, p. 225 - 231 (1985)

17O NMR spectra of fifteen cyclohexane-derived tertiary alcohols and related ethers and acetals, six 1,3-dioxane-derived orthoesters, four cyclohexane- and 1,3-dioxane-derived sulfones and the four corresponding sulfoxides, three acyclic sulfones, six alc

Cu2O-catalyzed C–S coupling of quaternary ammonium salts and sodium alkane-/arene-sulfinates

Chen, Hongyi,Huang, Youming,Zeng, Qingle,Zheng, Wenting

, (2020/08/28)

A new protocol for the synthesis of (enantioenriched) benzylic sulfones via the Cu2O-catalyzed C–S bond cross coupling of alkane-/arene-sulfinates and (enantioenriched) benzylic quaternary ammonium salts has been developed. The product benzylic sulfones were obtained in good to high yields (75–96%). Chiral arylmethyl sulfones with high enantiomeric excess (90–94% ee) were also synthesized in the presence of Cu2O and 1,1′-bis-(diphenylphosphino)ferrocene (dppf).
