Check Digit Verification of cas no
The CAS Registry Mumber 203385-99-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,8 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 203385-99:
(8*2)+(7*0)+(6*3)+(5*3)+(4*8)+(3*5)+(2*9)+(1*9)=123
123 % 10 = 3
So 203385-99-3 is a valid CAS Registry Number.

Synthesis of photosensitive EGTA derivatives
Ellis-Davies, Graham C. R.
, p. 953 - 956 (1998)
The syntheses of five derivatives of EGTA and one EGTA analogue are described. These molecules each have an ortho-nitrophenyl substituent positioned such that irradiation will cut the EGTA coordination sphere in two.
