Check Digit Verification of cas no

The CAS Registry Mumber 207690-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,6,9 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 207690-76:
(8*2)+(7*0)+(6*7)+(5*6)+(4*9)+(3*0)+(2*7)+(1*6)=144
144 % 10 = 4
So 207690-76-4 is a valid CAS Registry Number.

Convergent and stereoselective method for synthesis of O-linked oxepane ring system by intramolecular radical cyclization

Sasaki, Makoto,Inoue, Masayuki,Noguchi, Tetsuji,Takeichi, Atsuo,Tachibana, Kazuo

, p. 2783 - 2786 (2007/10/03)

A new strategy for the construction of O-linked oxepane ring system is described. The present method involves regioselective acetal cleavage by i- Bu2AlSePh and intramolecular radical cyclization by use of β- alkoxyacrylate.
