4940-48-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4940-48-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,4 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4940-48:
(6*4)+(5*9)+(4*4)+(3*0)+(2*4)+(1*8)=101
101 % 10 = 1
So 4940-48-1 is a valid CAS Registry Number.

Synthetic studies towards the preparation of 2-benzyl-2-hydroxybenzofuran- 3(2H)-one, the prototype of naturally occurring hydrated auronols

Loeser, Reik,Chlupacova, Marta,Marecek, Ales,Opletalova, Veronika,Guetschow, Michael

, p. 2597 - 2601 (2007/10/03)

Various synthetic approaches were employed to prepare 2-benzyl-2- hydroxybenzofuran-3(2H)-one (8), the prototype of naturally occurring auronols. While the base-induced ring transformation of 3-hydroxyflavanone (2) as well as the hydration of 2-benzylidenebenzofuran-3(2H)-one (=aurone; 6) proved to be inappropriate, the hydrogenolytic epoxide-ring opening of 2′- phenylspiro[benzofuran-2(3H),2′-oxiran]-3-one (7), obtained from 6, represents an efficient method to afford the auronol 8.
