Check Digit Verification of cas no

The CAS Registry Mumber 445473-99-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,4,7 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 445473-99:
(8*4)+(7*4)+(6*5)+(5*4)+(4*7)+(3*3)+(2*9)+(1*9)=174
174 % 10 = 4
So 445473-99-4 is a valid CAS Registry Number.

Design and syntheses of putative bioactive taxanes

Nikolakakis, Anastasia,Wu, Jian Hui,Batist, Gerald,Sauriol, Francoise,Mamer, Orval,Zamir, Lolita O.

, p. 2387 - 2395 (2007/10/03)

Reduction of 5α-hydroxy-7β,9α,10β-triacetoxy-4(20), 11(12)-taxadien-13-one 1 with activated zinc in glacial acetic acid led to rearranged products, including compounds with double bonds at C3-C4, C10-C11 or with an epoxide at C11-C12. Molecular modeling studies suggested that addition of a side chain at C-20 or C-5 of the taxanes with a C3-C4 double bond might lead to bioactivity. Semi-syntheses and results of bioactivities are discussed.
