Check Digit Verification of cas no

The CAS Registry Mumber 75277-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,7 and 7 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 75277-37:
(7*7)+(6*5)+(5*2)+(4*7)+(3*7)+(2*3)+(1*7)=151
151 % 10 = 1
So 75277-37-1 is a valid CAS Registry Number.

Photolyse d' arenesulfonates d' alkyle. Influence des bases et mecanisme de la reaction

Pete, Jean-Pierre,Portella, Charles

, p. 275 - 282 (2007/10/02)

Photolysis of alkyl arenesulfonates in various solvents leads to the corresponding alkyl alcohols in good chemical yields.Aromatic hydrocarbons and sulfur dioxide are also characterized in the reaction mixture.In the first step, homolysis of the C-S bond takes place from the sulfonate excited in a singlet state.In basic medium the reaction becomes cleaner and more efficient.Thr quenching of the fluorescence by NaOH, with 3 β-cholestanyl p-toluenesulfonate, seems to be diffusioncontrolled.The role of the base is discussed.
