342809-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 342809-19-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,2,8,0 and 9 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 342809-19:
(8*3)+(7*4)+(6*2)+(5*8)+(4*0)+(3*9)+(2*1)+(1*9)=142
142 % 10 = 2
So 342809-19-2 is a valid CAS Registry Number.

Process for producing onium salt derivative and novel onium salt derivative
-
, (2008/06/13)
The invention provides a high-yield method for producing onium salt derivatives useful as agents, such as acid-generators, employed in chemically amplified resists; and to provide novel onium salt derivatives. Reaction of an onium salt derivative containi
