Check Digit Verification of cas no
The CAS Registry Mumber 175441-49-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,4,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 175441-49:
(8*1)+(7*7)+(6*5)+(5*4)+(4*4)+(3*1)+(2*4)+(1*9)=143

Synthesis of 4-deacetyl-1-dimethylsilyl-7-triethylsilylbaccatin III
Ondari, Mark E.,Walker, Kevin D.
scheme or table, p. 2186 - 2188 (2009/08/07)
A one-pot trisilylation step to protect three hydroxyl groups of baccatin III (1), followed by hydride ester cleavage and base hydrolysis of a triethylsilyl ether at C13, provides efficient access to a key intermediate 9 (top path). This route removes two
