192520-16-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 192520-16-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,2,5,2 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 192520-16:
(8*1)+(7*9)+(6*2)+(5*5)+(4*2)+(3*0)+(2*1)+(1*6)=124
124 % 10 = 4
So 192520-16-4 is a valid CAS Registry Number.

Diastereoselective intramolecular Diels-Alder reactions towards the synthesis of a taxol C-ring precursor

Grimaud, Laurence,Ferezou, Jean-Pierre,Prunet, Joelle,Lallemand, Jean-Yves

, p. 9253 - 9268 (2007/10/03)

Intramolecular Diels-Alder reactions have been used for the synthesis of cis-hydroisobenzofuranones 23 or 21, which represents a potential precursor of taxol C-ring. Easy preparation of β-ketoesters 7a and 7b is also described.
