Check Digit Verification of cas no

The CAS Registry Mumber 143873-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,8,7 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143873-69:
(8*1)+(7*4)+(6*3)+(5*8)+(4*7)+(3*3)+(2*6)+(1*9)=152
152 % 10 = 2
So 143873-69-2 is a valid CAS Registry Number.

Manganese(II)/Picolinic Acid Catalyst System for Epoxidation of Olefins

Moretti, Ross A.,Du Bois,Stack, T. Daniel P.

supporting information, p. 2528 - 2531 (2016/07/06)

An in situ generated catalyst system based on Mn(CF3SO3)2, picolinic acid, and peracetic acid converts an extensive scope of olefins to their epoxides at 0 °C in 5 min, with remarkable oxidant efficiency and no evidence of radical behavior. Competition experiments indicate an electrophilic active oxidant, proposed to be a high-valent Mn = O species. Ligand exploration suggests a general ligand sphere motif contributes to effective oxidation. The method is underscored by its simplicity and use of inexpensive reagents to quickly access high value-added products.
