2209-92-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2209-92-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,0 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2209-92:
(6*2)+(5*2)+(4*0)+(3*9)+(2*9)+(1*2)=69
69 % 10 = 9
So 2209-92-9 is a valid CAS Registry Number.

Methylation of Polyols with Trimethylphosphate in the Presence of a Lewis or Br?nsted Acid Catalyst

Duclos, Marie-Christine,Herbinski, Aurélien,Mora, Anne-Sophie,Métay, Estelle,Lemaire, Marc

, p. 547 - 551 (2018/01/16)

The alkylation of alcohols and polyols has been investigated with alkylphosphates in the presence of a Lewis or Br?nsted acid catalyst. The permethylation of polyols was developed under solvent-free conditions at 100 °C with either iron triflate or Aquivion PW98, affording the isolated products in yields between 52 and 95 %. The methodology was also adjusted to carry out peralkylation with longer alkyl chains.
