123953-40-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 123953-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,9,5 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 123953-40:
(8*1)+(7*2)+(6*3)+(5*9)+(4*5)+(3*3)+(2*4)+(1*0)=122
122 % 10 = 2
So 123953-40-2 is a valid CAS Registry Number.

, (2008/06/13)
Photosensitive compounds having preferably a functional group such as --SO2 Cl, --SO3 H, --SO3 R, STR1 (R, R', R" being alkyl) on a terminal benzene or naphthalene ring connected via a methylene group and STR2 moiety are improved in sensitivity to light and thermal stability, and thus useful in a photo resist.
