223577-39-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 223577-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,3,5,7 and 7 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 223577-39:
(8*2)+(7*2)+(6*3)+(5*5)+(4*7)+(3*7)+(2*3)+(1*9)=137
137 % 10 = 7
So 223577-39-7 is a valid CAS Registry Number.

The living image: The efficient two-photon probes AZn1 and AZn2 (see picture for rat brain tissue) show 24-to 52-fold two-photon excited fluorescence enhancement in response to Zn2+. They can selectively detect intracellular free Zn2+ ions in live cells and in living tissues at a depth of 80-150 mm without interference from other metal ions and the membrane-bound probes.
