1191988-18-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1191988-18-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,1,9,8 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1191988-18:
(9*1)+(8*1)+(7*9)+(6*1)+(5*9)+(4*8)+(3*8)+(2*1)+(1*8)=197
197 % 10 = 7
So 1191988-18-7 is a valid CAS Registry Number.

Reusable and durable immobilized-cationic gold(I) catalysts for environmentally benign bond-forming reactions
Egi, Masahiro,Azechi, Kenji,Akai, Shuji
, p. 287 - 290 (2011)
Polystyrene-immobilized cationic gold catalysts 2a and 2b were synthesized for the first time and found to be highly effective catalysts for the bond-forming reactions via the activation of the Ci￡C triple bonds. The immobilized 2a was easily and quantita
