Check Digit Verification of cas no
The CAS Registry Mumber 72090-61-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,9 and 0 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 72090-61:
(7*7)+(6*2)+(5*0)+(4*9)+(3*0)+(2*6)+(1*1)=110
110 % 10 = 0
So 72090-61-0 is a valid CAS Registry Number.

4,4′-Benzophenone-O,O′-disulfamate: A potent inhibitor of steroid sulfatase
Nussbaumer, Peter,Bilban, Melitta,Billich, Andreas
, p. 2093 - 2095 (2007/10/03)
We investigated whether the benzophenone moiety can be used as core element of steroid sulfatase (STS) inhibitors. While 4- and 3-benzophenone-O-sulfamates inhibit STS with IC50 values between 5 and 7 μM irrespective of additional hydroxy and m
