188528-68-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 188528-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,5,2 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188528-68:
(8*1)+(7*8)+(6*8)+(5*5)+(4*2)+(3*8)+(2*6)+(1*8)=189
189 % 10 = 9
So 188528-68-9 is a valid CAS Registry Number.

Paclitaxel analogs modified in ring C: Synthesis and biological evaluation

Liang, Xian,Kingston, David G.I.,Long, Byron H.,Fairchild, Craig A.,Johnston, Kathy A.

, p. 3441 - 3456 (2007/10/03)

Lead tetracetate oxidation of 6α-hydroxy-7-epi-paclitaxel lends to C-nor-paclitaxel and C-seco-paclitaxel derivatives. Tetrpropylammonium perruthnate (TPAP) oxidation of a 6α-hydroxy-7-epi-paclitaxel derivative leads to a 6-formyl-C-nor-paclitaxel derivative. Reaction of a 6α-O-trifluoromethanesulfonyl-7-epi-paclitaxel derivative with DMAP yields a 20-O-acetyl-4-deacetyl-5,6-dehydro-6-formyl-C-nor-paclitaxel derivative. C-nor-paclitaxel analogs are less active than paclitaxel.
