Check Digit Verification of cas no
The CAS Registry Mumber 132806-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,8,0 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 132806-87:
(8*1)+(7*3)+(6*2)+(5*8)+(4*0)+(3*6)+(2*8)+(1*7)=122
122 % 10 = 2
So 132806-87-2 is a valid CAS Registry Number.

, p. 104 - 105 (1991)
Oxidation of p-methoxyphenols and 6-chromanols by copper(II) acetate in acetic acid gave the corresponding o-acetoxyphenols and 5-acetoxy-6-chromanols, which were easily hydrolysed in MeOH-H2O containing HCl to give catechol-type phenols.
