Check Digit Verification of cas no

The CAS Registry Mumber 519183-78-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,9,1,8 and 3 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 519183-78:
(8*5)+(7*1)+(6*9)+(5*1)+(4*8)+(3*3)+(2*7)+(1*8)=169
169 % 10 = 9
So 519183-78-9 is a valid CAS Registry Number.

A new route for the construction of the AB-ring core of Taxol

, p. 1401 - 1403 (2007/10/03)

A new method for the construction of the AB-ring core of Taxol was developed utilizing a new skeletal transformation protocol as a pivotal step. The acid-catalyzed rearrangement of the cyclopentenone-allene photoadduct gave a bridged seven-membered ketone, which was easily transformed, using the intramolecular Suzuki reaction and the oxidative cleavage of the vicinal diol, to the bicyclic diketone.
