Check Digit Verification of cas no

The CAS Registry Mumber 170456-60-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,4,5 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 170456-60:
(8*1)+(7*7)+(6*0)+(5*4)+(4*5)+(3*6)+(2*6)+(1*0)=127
127 % 10 = 7
So 170456-60-7 is a valid CAS Registry Number.

A high temperature investigation using microwave synthesis for electronically and sterically disfavoured substrates of the Newman-Kwart rearrangement

Moseley, Jonathan D.,Lenden, Philip

, p. 4120 - 4125 (2008/01/03)

Electronically deactivated and/or sterically hindered substrates undergo the Newman-Kwart rearrangement (NKR) at around 300 °C, beyond the range of most convenient and safe, small-scale laboratory equipment. We report here the convenient conversions of several difficult substrates using modern microwave technology, which has proven ideal for investigating this high temperature reaction in all but the?most refractory of cases. In addition, several previously reported difficult examples were re-investigated, and found not to require high temperatures under these conditions, for various reasons which are elaborated upon.
