Check Digit Verification of cas no

The CAS Registry Mumber 67287-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,2,8 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 67287-18:
(7*6)+(6*7)+(5*2)+(4*8)+(3*7)+(2*1)+(1*8)=157
157 % 10 = 7
So 67287-18-7 is a valid CAS Registry Number.

Functionalized hydroxyquinones through Suzuki-type coupling of phenyliodonium ylides of hydroxyquinones with arylboronic acids

Kazantzi, Georgia,Malamidou-Xenikaki, Elizabeth,Spyroudis, Spyros

, p. 2597 - 2600 (2008/09/16)

The palladium(II) acetate catalyzed reaction of phenyliodonium ylides of 2-hydroxyquinones with arylboronic acids affords a variety of 3-substituted 2-hydroxyquinone derivatives. Best yields are obtained by using tri(tert-butyl)phosphine as a ligand. Georg Thieme Verlag Stuttgart.
