189190-95-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 189190-95-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,1,9 and 0 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 189190-95:
(8*1)+(7*8)+(6*9)+(5*1)+(4*9)+(3*0)+(2*9)+(1*5)=182
182 % 10 = 2
So 189190-95-2 is a valid CAS Registry Number.

Synthesis and biological evaluation of amide-linked A-norpaclitaxels
Chordia, Mahendra D.,Kingston, David G. I.
, p. 5699 - 5710 (2007/10/03)
A novel amide-linked A-norpaclitaxel 3a and two 2-aroyl analogs 3b and 3c were prepared from 10-deacetyl baccatin III. Key steps in the synthesis were the conversion of 7-(triethylsilyl)baccatin m to its 13β-chloro-A-nor derivative 6, reaction with sodium
