Check Digit Verification of cas no

The CAS Registry Mumber 93222-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,2 and 2 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 93222-37:
(7*9)+(6*3)+(5*2)+(4*2)+(3*2)+(2*3)+(1*7)=118
118 % 10 = 8
So 93222-37-8 is a valid CAS Registry Number.

Bis(trifluoromethanesulfonimide) (BSI): Acidity and application to hydrofunctionalization as a Br?nsted acid catalyst

Takagi, Ryukichi,Sakai, Yuichiro,Duong, Duyen Thi

, (2021/03/23)

A binaphthyl derivative, bearing bis(trifluoromethanesulfonimide) (BSI) moiety, was developed as a novel Br?nsted acid. Computational prediction of the pKa value of BSI indicated its classification as a strong Br?nsted acid. BSI catalyzed the h

Paragraph 0316-0319, (2019/11/04)

The invention discloses a diaminodiphosphine tetradentate ligand and a ruthenium complex thereof, and preparation methods and applications of the ligand and the complex, and provides a ruthenium complex represented by a formula I, wherein L is a diaminodiphosphine tetradentate ligand represented by a formula II, and X and Y are respectively and independently chlorine ion, bromine ion, iodine ion,hydrogen negative ion or BH4. According to the present invention, the ruthenium complex exhibits excellent catalytic activity in the catalytic hydrogenation reactions of ester compounds, has high yield and high chemical selectivity, is compatible with conjugated and non-conjugated carbon-carbon double bond, carbon-carbon triple bond, epoxy, halogen, carbonyl and other functional groups, and hasgreat application prospects.

Double Functionalization of Styrenes by Cu-Mediated Assisted Tandem Catalysis

Kawauchi, Daichi,Ueda, Hirofumi,Tokuyama, Hidetoshi

supporting information, p. 2056 - 2060 (2019/03/13)

The double functionalization of styrenes through Cu-mediated assisted tandem catalysis was developed. The reaction was initiated by Cu-catalyzed aziridination and the subsequent nucleophilic ring-opening, which was triggered by the addition of (NH4)2S2O8 as an oxidant of Cu-catalyst to form a variety of C–C and C–X bonds. The expansion to three contiguous catalytic cycles led to the synthesis of functionalized indolines by one-pot operation.
