101703-83-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 101703-83-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,7,0 and 3 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 101703-83:
(8*1)+(7*0)+(6*1)+(5*7)+(4*0)+(3*3)+(2*8)+(1*3)=77
77 % 10 = 7
So 101703-83-7 is a valid CAS Registry Number.

Asymmetric desymmetrization of saturated and unsaturated meso-1,2-diols

Fujioka, Hiromichi,Nagatomi, Yasushi,Kotoku, Naoyuki,Kitagawa, Hidetoshi,Kita, Yasuyuki

, p. 10141 - 10151 (2007/10/03)

An asymmetric desymmetrization of saturated and unsaturated cyclic and acyclic meso-1,2-diols has been developed from the ene acetals, prepared from the norbornene carboxyaldehyde and meso-1,2-diols. The intramolecular haloetherification of the ene acetals as a key step afforded 8-membered acetals in a stereoselective manner just by the reaction of norbornene olefin even when the ene acetals from unsaturated meso-1,2-diols having olefins in the same molecule were used. Subsequent reductive elimination, followed by protecting the hydroxy group and transacetalization, gave optically active 1,2-diol derivatives and the starting ene acetals in good yields.
