Check Digit Verification of cas no

The CAS Registry Mumber 890903-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,0,9,0 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 890903-54:
(8*8)+(7*9)+(6*0)+(5*9)+(4*0)+(3*3)+(2*5)+(1*4)=195
195 % 10 = 5
So 890903-54-5 is a valid CAS Registry Number.

Palladium-catalyzed asymmetric ring expansion of allenylcyclobutanols: An asymmetric Wagner-Meerwein shift

Trost, Barry M.,Xie, Jia

, p. 6044 - 6045 (2006)

In this study, we developed a palladium-catalyzed atom economic asymmetric Wagner-Meerwein shift of allenylcyclobutanol substrates. It is an excellent method for creating functionalized cyclopentanones with an α-chiral O-tertiary center by ring expansion
