Check Digit Verification of cas no

The CAS Registry Mumber 71916-06-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,9,1 and 6 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 71916-06:
(7*7)+(6*1)+(5*9)+(4*1)+(3*6)+(2*0)+(1*6)=128
128 % 10 = 8
So 71916-06-8 is a valid CAS Registry Number.

Ketone-derived Peroxides. Part I. Synthetic Methods.

McCullough, Kevin J.,Morgan, Alistair R.,Nonhebel, Derek C.,Pauson, Peter L.,White, Graham J.

, p. 601 - 628 (2007/10/02)

Study of the reactivity of peroxides derivable from ketones by reaction with hydrogen peroxide has required reexamination of preparative methods.Conditions for obtaining five known peroxides from cyclohexanone and the new 1-(1-hydroxycyclohexyldioxy)-1-(1-hydroperoxycyclohexyldioxy)cyclohexane (10) are carefully defined.An improved general method for obtaining cyclic diperoxides (3,3,6,6-tetrasubstituted 1,2,4,5-tetraoxans) (6) has been developed and used to obtain new diperoxides from dibenzyl ketone, di-(4-methylbenzyl) ketone and 2,2-dimethylcyclohexanone whereas indan-2-one and 5,7-dihydro-6H-dibenzocyclohepten-6-one yield the corresponding triperoxides (1,2,4,5,7,8-hexoxonans) (7) and 1,5-diphenylpentan-3-one yields bis-(1-hydroperoxy-1-phenethyl-3-phenylpropyl) peroxide (5k).Ozonolysis of appropriate alkenes has been used to obtain new cyclic diperoxides formally related to 4'-methylacetophenone, propiophenone and deoxybenzoin.
