Check Digit Verification of cas no

The CAS Registry Mumber 258871-95-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,8,7 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 258871-95:
(8*2)+(7*5)+(6*8)+(5*8)+(4*7)+(3*1)+(2*9)+(1*5)=193
193 % 10 = 3
So 258871-95-3 is a valid CAS Registry Number.

RADIATION-SENSITIVE COMPOSITION OF CHEMICAL AMPLIFICATION TYPE

-

, (2008/06/13)

A chemically amplified radiation sensitive composition is provided which comprises a film forming hydroxystyrene based resin in combination with an onium salt precursor which generates a fluorinated alkanesulfonic acid as a photoacid generator. This composition can realize neither corrosion of apparatuses by outgas, nor T-shaped pattern profiles, nor change in linewidth attributable to process time delay, on the other side, high sensitivity and resolution, and good pattern profiles and stability thereof.
