Check Digit Verification of cas no

The CAS Registry Mumber 1157166-84-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,5,7,1,6 and 6 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1157166-84:
(9*1)+(8*1)+(7*5)+(6*7)+(5*1)+(4*6)+(3*6)+(2*8)+(1*4)=161
161 % 10 = 1
So 1157166-84-1 is a valid CAS Registry Number.

Oxidative iodination of carbonyl compounds using ammonium iodide and oxone

Marri, Mahender Reddy,MacHarla, Arun Kumar,Peraka, Swamy,Nama, Narender

, p. 6554 - 6559 (2011)

A simple, efficient, mild, and regioselective method for oxyiodination of carbonyl compounds has been reported by using NH4I as the source of iodine and Oxone as an oxidant. Various carbonyl compounds such as aralkyl ketones, aliphatic ketones (acyclic and cyclic), and β-keto esters proceeded to the respective α-monoiodinated products in moderate to excellent yields. Unsymmetrical aliphatic ketones reacted smoothly yielding a mixture of 1-iodo and 3-iodo ketones with the predominant formation of 1-iodoproduct.
