Check Digit Verification of cas no
The CAS Registry Mumber 13475-09-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13475-09:
(7*1)+(6*3)+(5*4)+(4*7)+(3*5)+(2*0)+(1*9)=97
97 % 10 = 7
So 13475-09-7 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
