Check Digit Verification of cas no
The CAS Registry Mumber 202289-38-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,2,8 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 202289-38:
(8*2)+(7*0)+(6*2)+(5*2)+(4*8)+(3*9)+(2*3)+(1*8)=111
111 % 10 = 1
So 202289-38-1 is a valid CAS Registry Number.

Bis(2-methoxyethyl)aminosulfur trifluoride: A new broad-spectrum deoxofluorinating agent with enhanced thermal stability

Bis(2-methoxyethyl)aminosulfur trifluoride (Deoxo-Fluor) is effective for the conversion of alcohols to alkyl fluorides, aldehydes/ketones to the corresponding gem-difluorides and also for the transformation of carboxylic acids to their trifluoromethyl derivatives; it is a less thermally sensitive, broader-spectrum alternative to the traditional dialkylaminosulfur trifluoride (DAST) deoxofluorination reagents.
