486991-89-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 486991-89-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,8,6,9,9 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 486991-89:
(8*4)+(7*8)+(6*6)+(5*9)+(4*9)+(3*1)+(2*8)+(1*9)=233
233 % 10 = 3
So 486991-89-3 is a valid CAS Registry Number.

Synthesis of C-3′ methyl taxotere (docetaxel)
Lucatelli, Christophe,Viton, Florian,Gimbert, Yves,Greene, Andrew E.
, p. 9468 - 9470 (2007/10/03)
Protected (3R,4S)-N-Boc-3-hydroxy-4-methyl-4-phenylazetidin-2-one has been synthesized stereoselectively and used to esterify protected 10-desacetylbaccatin III to give, following removal of the protecting groups, novel C-3′ methyl taxotere (docetaxel).
