270563-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 270563-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,0,5,6 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 270563-50:
(8*2)+(7*7)+(6*0)+(5*5)+(4*6)+(3*3)+(2*5)+(1*0)=133
133 % 10 = 3
So 270563-50-3 is a valid CAS Registry Number.

Mechanism on one-sided Wessely-Moser rearrangement reaction
Shinomiya, Kazuki,Hano, Yoshio,Nomura, Taro
, p. 877 - 886 (2007/10/03)
Wessely-Moser rearrangement reaction of 5,7-dihydroxychromone derivatives with an isopentyl side chain at C-6 or C-8 position was examined. All reactions gave 8-isopentylchromone derivative predominantly as rearrangement product. Kinetic analysis of the o
