Check Digit Verification of cas no

The CAS Registry Mumber 1071156-77-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,1,1,5 and 6 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1071156-77:
(9*1)+(8*0)+(7*7)+(6*1)+(5*1)+(4*5)+(3*6)+(2*7)+(1*7)=128
128 % 10 = 8
So 1071156-77-8 is a valid CAS Registry Number.

FACTORS GOVERNING PRODUCT DISTRIBUTION IN THE OXIDATION OF ALKENES BY MANGANESE(III) ACETATE IN ACETIC ACID AND ACETIC ANHYDRIDE

Midgley, Gary,Thomas, C. Barry

, p. 1537 - 1544 (2007/10/02)

A systematic investigation has been carried out into the effect of different reaction parameters on the oxidation of oct-1-ene by manganese(III) acetate in acetic acid and acetic anhydride.The most important factor in dictating the ratio of products is the composition of the solvent.In the absence of anhydride γ-decanolactone is virtually the sole product.Even small quantitites of anhydride lead to the lactone being replaced by other products derived from cationic intermediates C6H13CH(1+)CH2COX (X = OH or OAc).Further increases in the amount of anhydride encourage the formation of decanoic acid until, in 90percent anhydride, this becomes the predominant product.The results cannot be interpreted simply in terms of competition for the alkene by the radicals (.)CH2CO2H and (.)CH2COOCOCH3.Decanoic acid formation is also favoured by low temperatures, low concentration of oxidants, and by the addition of acetate ions.A comparision is made of the efficiency of addition when the initiating species is manganese(III) or a peroxide.
