Check Digit Verification of cas no

The CAS Registry Mumber 208708-80-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,7,0 and 8 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 208708-80:
(8*2)+(7*0)+(6*8)+(5*7)+(4*0)+(3*8)+(2*8)+(1*0)=139
139 % 10 = 9
So 208708-80-9 is a valid CAS Registry Number.

Diastereo-differentiating coupling of phenoxy radical moiety controlled by 2,4-pentanediol tether. Preparation of optically active Pummerer's ketone analogs

Yamaguchi, Kohei,Sugimura, Takashi,Nishida, Futoshi,Tai, Akira

, p. 4521 - 4524 (2007/10/03)

The highly diastereo-differentiating coupling of the phenoxy radical could be achieved by a 2,4-pentanediol tethered reaction to give a single diastereomer of Pummerer's ketone analog. By the removal of the chiral auxiliary, the optically active phenoxy radical direct was obtained in good yield.
