Check Digit Verification of cas no

The CAS Registry Mumber 90766-75-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,7,6 and 6 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90766-75:
(7*9)+(6*0)+(5*7)+(4*6)+(3*6)+(2*7)+(1*5)=159
159 % 10 = 9
So 90766-75-9 is a valid CAS Registry Number.

Butenolide annelation using a manganese(III) oxidation. A synthesis of 4-arylfuran-2(5H)-ones

Demir, Ayhan S.,Camkerten, Nurettin,Gercek, Zuhal,Duygu, Nese,Reis, Omer,Arikan, Elif

, p. 2441 - 2448 (2007/10/03)

A general procedure was developed for the annelation of a butenolide to an aromatic ketone that highlighted a manganese(III) oxidation of aromatic ketones. The oxidation of aromatic ketones with manganese(III) acetate in the presence of 2-bromoacetic acid or the Mn(II) salt of this carboxylic acid provided a regioselectively convenient synthesis of 2-(2-bromoacetoxy) ketones. An Arbuzov or Wittig reaction of 2-(2-bromoacetoxy) ketones followed by cyclisation furnished 4-arylfuran-2(5H)-ones in good yield.
