Check Digit Verification of cas no

The CAS Registry Mumber 104515-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,1 and 5 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104515-61:
(8*1)+(7*0)+(6*4)+(5*5)+(4*1)+(3*5)+(2*6)+(1*1)=89
89 % 10 = 9
So 104515-61-9 is a valid CAS Registry Number.

Intramolecular 1,4-Dipolar Cycloadditions utilizing Heteroaromatic Betaines

Potts, Kevin T.,Dery, Maurice O.

, p. 563 - 565 (1986)

anhydro-2-(2-Allyloxyphenyl)-3,5-diphenyl-4-hydroxy-6-oxo-1,3-thiazinium hydroxide and the corresponding ethynyl derivative underwent ready thermal 1,4-dipolar cycloaddition to give a 1:1-cycloadduct (whose structure was determined by X-ray crystallograph

Pyrolysis of O-Allyl Salicylic Amides and Esters, and Related Compounds: Foemation of Isoindolones and Phthalides

Black, Michael,Cadogan, J. I. G.,McNab, Hamish

, p. 155 - 160 (2007/10/02)

Flash vacuum pyrolysis of O-allyl salicylic alkylamides and alkyl esters gives isoindolones and phthalides, respectively, in low (20-40percent) yield.The mechanism involves generation of the phenoxyl radical, regiospecific hydrogen-atom transfer from the alkylamide (or alkyl ester) group and cyclization.A similar sequence was observed with thiophenoxyl radicals.
