Check Digit Verification of cas no

The CAS Registry Mumber 118043-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,0,4 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 118043-80:
(8*1)+(7*1)+(6*8)+(5*0)+(4*4)+(3*3)+(2*8)+(1*0)=104
104 % 10 = 4
So 118043-80-4 is a valid CAS Registry Number.

Thermal and Photochemical Reactions of Triarylmethyl Peroxides

Neckers, D.C.,Linden, Shwn-Meei,Williams, B. Lee,Zakrzewski, Andrzej

, p. 131 - 135 (2007/10/02)

The thermal and photochemical decomposition products of p-benzoyltriphenylmethyl peroxide (I), of m-benzoyltriphenylmethyl peroxide (II), and of isotopically labeled analogues indicate rapid radical 1,2-migrations precluding other radical processes such as β-elimination from the incipient radical.The mechanism of these processes is interpreted in terms of these rearrangements as well as reversible elimination of O2 from the starting peroxide.Differences in the two isomeric peroxides are assessed.
