Check Digit Verification of cas no

The CAS Registry Mumber 208044-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,0,4 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 208044-43:
(8*2)+(7*0)+(6*8)+(5*0)+(4*4)+(3*4)+(2*4)+(1*3)=103
103 % 10 = 3
So 208044-43-3 is a valid CAS Registry Number.

Enantiospecific total synthesis of natural (+)-taxusin. 2. Functionalization of the A-ring and arrival at the target

Paquette, Leo A.,Wang, Hui-Ling,Su, Zhuang,Zhao, Mangzhu

, p. 5213 - 5225 (2007/10/03)

A total synthesis of (+)-taxusin (1) has been realized by virtue of the development of a practical route for complete functionalization of the A ring. To achieve this goal, it proved necessary to devise a strategy that would enable chemical transformation
