It is a fluorogenic substrate for albumin esterase activity. [Chen & Scott Anal Lett 17 857 1984.] At 320nm it has fluorescence at 500nm. ex em [Brass & Sommer Chem Ber 61 1000 1928, Beilstein 12 II 260, 12 III 960, 12 IV 923.]
Check Digit Verification of cas no
The CAS Registry Mumber 1163-67-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,6 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1163-67:
(6*1)+(5*1)+(4*6)+(3*3)+(2*6)+(1*7)=63
63 % 10 = 3
So 1163-67-3 is a valid CAS Registry Number.
