Check Digit Verification of cas no

The CAS Registry Mumber 31599-61-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,5,9 and 9 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 31599-61:
(7*3)+(6*1)+(5*5)+(4*9)+(3*9)+(2*6)+(1*1)=128
128 % 10 = 8
So 31599-61-8 is a valid CAS Registry Number.

Pronounced catalytic effect of micellar solution of sodium dodecyl sulfate (SDS) for regioselective iodination of aromatic compounds with a sodium iodide/cerium(IV) trihydroxide hydroperoxide system

Firouzabadi, Habib,Iranpoor, Nasser,Garzan, Atefeh

, p. 1925 - 1928 (2005)

Micellar solutions of sodium dodecyl sulfate (SDS) catalyze the regioselective iodination of a wide range of aromatic compounds with sodium iodide in the presence of the easily prepared, water-resistant and recyclable cerium(IV) trihydroxide hydroperoxide, Ce(OH)3O2H, at room temperature. By this protocol, structurally diverse aromatic compounds including benzene and naphthalene were iodinated in good to excellent yields.

PURIFIED CRYSTALLINE DETOMIDINE HYDROCHLORIDE MONOHYDRATE, ANHYDRATE AND FREE BASE WITH LOW AMOUNTS OF ISO-DETOMIDINE AND OTHER IMPURITIES BY RECRYSTALLISATION IN WATER

-

Page/Page column 26; 27, (2020/02/14)

The present disclosure relates to crystalline detomidine hydrochloride monohydrate, anhydrous detomidine hydrochloride and detomidine free base (4-[(2,3-dimethylphenyl)methyl]-1H-lmidazole ), purified by recrystallisation in water, with a low amount (total amount of impurities is not more than 0.1% area relative to detomidine based on HPLC, UV detection at 220 nm) of the impurities iso-detomidine (4-[(3,4-dimethylphenyl)methyl]-1H-lmidazole ), iso-impurity A (((RS)-(3,4-dimethylphenyl)(1H-imidazol-4-yl)methanol)), impurity A ((RS)-(2,3-dimethylphenyl)(1H-imidazol-4-yl)methanol), "ketone impurity" (2,3-dimethylphenyl)(1H-imidazol-4-yl) methanone, impurity B ((RS)-(1-benzyl-1H-imidazol-5-yl)(2, 3-dimethyl phenyl) methanol) and impurity C (4-[(2,3-dimethylcyclohexyl)methyl]-1H-imidazole). Also disclosed are processes for recrystallising detomidine hydrochloride monohydrate from commercially available anhydrous detomidine hydrochloride in water, pharmaceutical compositions comprising detomidine hydrochloride in purified form for use as an analgesic in methods of treating human subjects, a process for validating a batch of detomidine hydrochloride drug substance by determining the content of impurities iso-detomidine and iso- impurity A by HPLC, as well as XRPD, DSC and TGA data of crystalline detomidine free base.

Disulfide-Catalyzed Iodination of Electron-Rich Aromatic Compounds

Iida, Keisuke,Ishida, Shunsuke,Watanabe, Takamichi,Arai, Takayoshi

, p. 7411 - 7417 (2019/06/18)

Herein, a disulfide-catalyzed electrophilic iodination of aromatic compounds using 1,3-diiodo-5,5-dimethylhydantoin (DIH) has been developed. The disulfide activates DIH as a Lewis base to promote the iodination reaction in acetonitrile under mild conditions. This system is applicable to a wide range of electron-rich aromatic compounds, including acetanilide, anisole, imidazole, and pyrazole derivatives.
