Check Digit Verification of cas no

The CAS Registry Mumber 1026328-70-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,6,3,2 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1026328-70:
(9*1)+(8*0)+(7*2)+(6*6)+(5*3)+(4*2)+(3*8)+(2*7)+(1*0)=120
120 % 10 = 0
So 1026328-70-0 is a valid CAS Registry Number.

Enantioselective synthesis of goniobutenolides A and B

Ko, Soo Y.,Lerpiniere, Joanne

, p. 2101 - 2104 (1995)

Goniobutenolides A and B were synthesized in the enantiopure forms, employing the asymmetric dihydroxylation and cyclic sulfate rearrangement-opening reactions as the key stereocenter-forming steps.

An Access to erythro-Diols via Sharpless's Asymmetric Dihydroxylation Reaction

Ko, Soo Y.,Malik, Majbeen,Dickinson, A. Frances

, p. 2570 - 2576 (2007/10/02)

A method has been developed to access erythro-2,3-diols via Sharpless's asymmetric dihydroxylation reaction.Thus, a TBDMS-protected (E)-allylic alcohol is dihydroxylated and the resulting threo-2,3-diol is converted to the cyclic sulfate.Upon desilylation, this compound undergoes a Payne-type rearrangement.Nucleophilic epoxide-opening then provides an erythro-2,3-diol.The conversions from the cyclic sulfate to the diol product are performed in a single reaction vessel.Due to the irreversible nature of the Payne-type rearrangement, this process is easy to perform and completely regioselective independent of the substrate structures.Also, being performed in THF, the process is compatible with a variety of nucleophiles, including thiolates, -N3, -OAc, -CN, halides as well as carbon nucleophiles and hydride.
