4017-83-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4017-83-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,1 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4017-83:
(6*4)+(5*0)+(4*1)+(3*7)+(2*8)+(1*3)=68
68 % 10 = 8
So 4017-83-8 is a valid CAS Registry Number.

Stereoselective Synthesis of Carane-Type Hydroxythiols and Disulfides Based on Them

Banina,Sudarikov,Slepukhin,Frolova,Kuchin

, p. 240 - 247 (2016/07/06)

Isomeric 10-sulfanylcaran-4-ols and 4-sulfanylcaran-3-ols were synthesized and used to prepare disulfides in high yields.

Synthesis of chiral thienylpyridines from naturally occurring monoterpenes: Useful ligands for cyclometallated complexes

Gianini, Michel,Von Zelewsky, Alex

, p. 702 - 706 (2007/10/03)

On treatment with ammonium acetate, α,β-unsaturated ketones or aldehydes can easily undergo condensation with acetylpyridinium salts (Krohnke reaction). Four 'thienylpyridine' ligands, derived from (-)-β-pinene, (+)-camphor, (+)-3-carene and (+)-2-carene, were prepared according to this method. The multistep syntheses to get (1R,5R)-3-methylenenopinone (5), (+)-3-methylenecamphor (10), (-)-3-caren-10-al (15) and (1S,6R)-7,7-dimethyl-3-methylenebicyclo[4.1.0]heptan-2-one (18) are also described.
