Check Digit Verification of cas no
The CAS Registry Mumber 1998-61-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1998-61:
(6*1)+(5*9)+(4*9)+(3*8)+(2*6)+(1*1)=124
124 % 10 = 4
So 1998-61-4 is a valid CAS Registry Number.

P-Hydroxyphenacyl photoremovable protecting groups Robust photochemistry despite substituent diversity

scheme or table, p. 364 - 384 (2011/06/22)
A broadly based investigation of the effects of a diverse array of substituents on the photochemical rearrangement of p-hydroxyphenacyl esters has demonstrated that common substituents such as F, MeO, CN, CO2R, CONH2, and CH3 have little effect on the rate and quantum efficiencies for the photo-Favorskii rearrangement and the release of the acid leaving group or on the lifetimes of the reactive triplet state. A decrease in the quantum yields across all substituents was observed for the release and rearrangement when the photolyses were carried out in buffered aqueous media at pHs that exceeded the ground-state pKa of the chromophore where the conjugate base is the predominant form. Otherwise, substituents have only a very modest effect on the photoreaction of these robust chromophores.
Simple bromination of activated arenes by IBX amide resin and tetraethyl-ammonium bromide
Kim, Duk-Ki,Chung, Woo-Jae,Lee, Yoon-Sik
, p. 279 - 282 (2007/10/03)
A mild and operationally simple method of brominating activated aromatic compounds using a polymer supported IBX reagent (IBX amide resin) and tetraethylammonium bromide (TEAB) was developed. The activated aromatics, when reacted with IBX amide resin in the presence of TEAB, were easily converted into the brominated aromatics in high yields (>80%) at room temperature.
