73671-56-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73671-56-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,6,7 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 73671-56:
(7*7)+(6*3)+(5*6)+(4*7)+(3*1)+(2*5)+(1*6)=144
144 % 10 = 4
So 73671-56-4 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.
