Check Digit Verification of cas no

The CAS Registry Mumber 76711-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,7,1 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 76711-49:
(7*7)+(6*6)+(5*7)+(4*1)+(3*1)+(2*4)+(1*9)=144
144 % 10 = 4
So 76711-49-4 is a valid CAS Registry Number.

A stereocontrolled approach towards highly oxygenated taxane C and CD-ring precursors

Uttaro, Jean-Pierre,Audran, Gérard,Galano, Jean-Marie,Monti, Honoré

, p. 2757 - 2760 (2002)

Based upon a remarkable β-face diastereoselection, a stereocontrolled construction of bicyclic systems with the appropriate stereochemical disposition of the substituents belonging either to a Baccatin-I C-ring precursor or a Taxol CD-ring precursor is reported.

Synthetic studies on the ambiguine family of alkaloids: Construction of the ABCD ring system

Rafferty, Ryan J.,Williams, Robert M.

supporting information; experimental part, p. 2037 - 2040 (2011/05/09)

A racemic synthesis of the ABCD ring core of the ambiguines that preserves the tertiary alcohol has been accomplished in a convergent synthesis in 10 synthetic steps, in an overall yield of 46% from commercially available 4-bromoindole and m-methylanisole
