81698-99-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 81698-99-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,9 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81698-99:
(7*8)+(6*1)+(5*6)+(4*9)+(3*8)+(2*9)+(1*9)=179
179 % 10 = 9
So 81698-99-9 is a valid CAS Registry Number.

Stille couplings in water at room temperature

Lu, Guo-Ping,Cai, Chun,Lipshutz, Bruce H.

supporting information, p. 105 - 109 (2013/02/23)

A nonionic amphiphile, TPGS-750-M, enables efficient Stille couplings between a wide range of substrates to be conducted in water as the only medium, in most cases at room temperature.

Gold catalysis: No steric limitations in the phenol synthesis

Hashmi, A. Stephen K.,Salathe, Ralph,Frey, Wolfgang

, p. 6991 - 6996 (2007/10/03)

Different dihydroisoindol-4-ols and 8-hydroxytetrahydroisoquinolines were prepared by the gold-catalyzed phenol synthesis. The reaction was investigated with several sterically demanding groups in the 5-position of the furan starting material. The influen
