Check Digit Verification of cas no

The CAS Registry Mumber 121732-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,3 and 2 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 121732-94:
(8*1)+(7*2)+(6*1)+(5*7)+(4*3)+(3*2)+(2*9)+(1*4)=103
103 % 10 = 3
So 121732-94-3 is a valid CAS Registry Number.

A New Synthesis of ortho-Quinones by Transition-Metal-Mediated Oxygenation of Phenols with tert-Butylhydroperoxide and the Mimoun Oxodiperoxo Molybdenum Complex * Py * HMPT

Krohn, Karsten,Rieger, Hagen,Khanbabaee, Karamali

, p. 2323 - 2330 (2007/10/02)

A specific oxygenation of phenols to ortho-quinones can be effected by a combination of the transition metal complexes Ti(OiPr)4, VO(acac)2, Zr(acac)4, Zr(OnPr)4 and tert-butylhydroperoxide (TBHP) or * Py * HMPT.Naphthols, anthracenols, phenanthrols and donor substituted mononuclear phenols are readily converted into the corresponding 1,2-quinones.Unhindered ortho-naphthoquinones can yield binaphthyls with unreacted starting material by Michael addition. - Key Words: ortho-Quinones / tert-Butyl hydroperoxide / Phenols, oxygenation
