103687-47-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 103687-47-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,6,8 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 103687-47:
(8*1)+(7*0)+(6*3)+(5*6)+(4*8)+(3*7)+(2*4)+(1*7)=124
124 % 10 = 4
So 103687-47-4 is a valid CAS Registry Number.

STEREOCHEMISTRY OF SOME REACTIONS BETWEEN ALKYL S-METHYL METHYLPHOSPHONOTHIOATES AND CHIRAL ALKOXIDES

Hall, C. Richard,Inch, Thomas D.,Pottage, Colin,Williams, Nancy E.

, p. 4909 - 4918 (1985)

With R-(+) ethyl (or methyl) S-methyl methylphosphonothioate and (+)-pinacolyl alkoxide competitive and highly stereoselective displacements of O-alkyl and S-methyl occur, both reactions being with inversion of configuration.With the enantiomeric S-(-) ethyl (and methyl) S-methyl methylphosphonothioates and (+)-pinacolyl alkoxide the reactions, although still competitive, are no longer stereoselective.In contrast similar reactions with the sodium salt of (-)-menthol, (which might be considered to be the mirror image of (+)-pinacolyl alkoxide) occur highly stereoselectively with the S-(-) but not with R-(+) enantiomers.The displacement of O-alkyl from alkyl S-methyl methylphosphonothioates by ethoxide, pinacolyl alkoxide and menthyl alkoxide is not observed when methoxide is the nucleophile; in this case only displacement of S-alkyl group occurs.
