Check Digit Verification of cas no

The CAS Registry Mumber 91715-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,7,1 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 91715-77:
(7*9)+(6*1)+(5*7)+(4*1)+(3*5)+(2*7)+(1*7)=144
144 % 10 = 4
So 91715-77-4 is a valid CAS Registry Number.

Direct ortho-acetoxylation of anilides via palladium-catalyzed sp 2 C-H bond oxidative activation

Wang, Guan-Wu,Yuan, Ting-Ting,Wu, Xue-Liang

, p. 4717 - 4720 (2008/09/21)

(Chemical Equation Presented) Various anilides have been directly ortho-acetoxylated through a Pd(OAc)2-catalyzed C-H bond activation process. The amide group in anilides was found to functionalize as an elegant directing group to convert aromatic sp2 C-H bonds into C-O bonds in high regioselectivity with acetic acid as the acetate source and K 2S2O8 as the oxidant.

Improved Syntheses of Some Monohloro- and Monobromo-8-quinolinols

Gershon, Herman,Clarke, Donald D.

, p. 935 - 942 (2007/10/02)

Procedures were developed for the preparation of the 2-, 3-, 4-, and 6-monosubstituted chloro and bromo 8-quinolinols which afforded greater yields and/or reduced the number of steps in the preparation. 100 MHz 1H-NMR spetra for the 12 possible monochloro
