Check Digit Verification of cas no
The CAS Registry Mumber 205443-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,4,4 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 205443-08:
(8*2)+(7*0)+(6*5)+(5*4)+(4*4)+(3*3)+(2*0)+(1*8)=99
99 % 10 = 9
So 205443-08-9 is a valid CAS Registry Number.

Synthesis and photochemistry of two cleavable heterobifunctional benzophenone protein crosslinkers
Oatis Jr., John E.,Knapp, Daniel R.
, p. 1665 - 1668 (2007/10/03)
Two new heterobifunctional protein crosslinkers were synthesized. These reagents contain the cysteine reactive maleimido group connected via a cleavable ester linkage to the benzophenone photoactivatable group.
