Check Digit Verification of cas no

The CAS Registry Mumber 916260-84-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,6,2,6 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 916260-84:
(8*9)+(7*1)+(6*6)+(5*2)+(4*6)+(3*0)+(2*8)+(1*4)=169
169 % 10 = 9
So 916260-84-9 is a valid CAS Registry Number.

Cu-catalyzed esterification reaction via aerobic oxygenation and C-C bond cleavage: An approach to α-ketoesters

Zhang, Chun,Feng, Peng,Jiao, Ning

supporting information, p. 15257 - 15262 (2013/11/06)

The Cu-catalyzed novel aerobic oxidative esterification reaction of 1,3-diones for the synthesis of α-ketoesters has been developed. This method combines C-C σ-bond cleavage, dioxygen activation and oxidative C-H bond functionalization, as well as provides a practical, neutral, and mild synthetic approach to α-ketoesters which are important units in many biologically active compounds and useful precursors in a variety of functional group transformations. A plausible radical process is proposed on the basis of mechanistic studies.
