Check Digit Verification of cas no

The CAS Registry Mumber 140706-18-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,7,0 and 6 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 140706-18:
(8*1)+(7*4)+(6*0)+(5*7)+(4*0)+(3*6)+(2*1)+(1*8)=99
99 % 10 = 9
So 140706-18-9 is a valid CAS Registry Number.

The synthesis of chiral α,β-unsaturated and aryl oxazolines from ketones and arols via their triflates and Pd-catalyzed CO and amino alcohol coupling

Meyers,Robichaud,McKennon

, p. 1181 - 1184 (2007/10/02)

An efficient route to the title compounds was achieved using the triflates of ketones and phenols followed by Pd-catalyzed CO insertion in the presence of chiral amino alcohols. Aryl, vinyl bromides and 2-pyridone also served as useful substrates.
