Check Digit Verification of cas no
The CAS Registry Mumber 57835-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,8,3 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 57835-99:
(7*5)+(6*7)+(5*8)+(4*3)+(3*5)+(2*9)+(1*9)=171
171 % 10 = 1
So 57835-99-1 is a valid CAS Registry Number.

Microwave-assisted formation of sulfonium photoacid generators

Page/Page column 8, (2012/06/16)
Efficient method for preparing sulfonium photoacid generators (PAGs) by microwave-assisted reaction of diarylsufides in the presence of alkylaryliodonium salts. Microwave-assisted synthesis of the PAGs is significantly faster, reducing reaction time with less energy consumption. Reaction times using the microwave-assisted synthesis are in a range of from 90 to 420 faster than conventional thermal conditions. The photoacid quantum yields of several salts prepared by the microwave reaction were measured; the photoacid quantum yields of new sulfonium PAGs were in a range from 0.01 to 0.4 times greater than yields from conventional synthesis. Incorporating a nitro group in the structures of the sulfonium salts increased photoacid quantum yield, induced intersystem crossing and increased the efficiency of photoacid generation compounds.
