Check Digit Verification of cas no

The CAS Registry Mumber 115419-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,4,1 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 115419-58:
(8*1)+(7*1)+(6*5)+(5*4)+(4*1)+(3*9)+(2*5)+(1*8)=114
114 % 10 = 4
So 115419-58-4 is a valid CAS Registry Number.

Ligand-free Cu(ii)-mediated aerobic oxidations of aldehyde hydrazones leading to N,N′-diacylhydrazines and 1,3,4-oxadiazoles

Liu, Lei,Feng, Suliu

supporting information, p. 2585 - 2592 (2017/04/03)

A Cu(ii)-mediated synthesis of N,N′-diacylhydrazines and 1,3,4-oxadiazoles from aldehyde hydrazones has been developed. This is the first time that the synthesis of N,N′-diacylhydrazines and 1,3,4-oxadiazoles using N,N-dimethylamides as the acylation reagent and O2 in air as the oxidation reagent is reported. These reactions offered several advantages including simple workups, ligand-free inexpensive metal salts as mediators, high yields, and wide scope of substrates.
