Check Digit Verification of cas no

The CAS Registry Mumber 70637-61-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,6,3 and 7 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 70637-61:
(7*7)+(6*0)+(5*6)+(4*3)+(3*7)+(2*6)+(1*1)=125
125 % 10 = 5
So 70637-61-5 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.
