Check Digit Verification of cas no

The CAS Registry Mumber 90195-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,9 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90195-20:
(7*9)+(6*0)+(5*1)+(4*9)+(3*5)+(2*2)+(1*0)=123
123 % 10 = 3
So 90195-20-3 is a valid CAS Registry Number.

Synthesis and Binding Studies of Crown Ethers Bearing Pharmacophoric Groups: Epoxy Lariat Crown Ethers

Jarvis, Bruce B.,Vrudhula, Vivekananda M.,Dishong, Dennis M.,Gokel, George W.

, p. 2423 - 2427 (2007/10/02)

A series of lariat ethers (derivatives of 18-crown-6, 15-crown-5, and 12-crown-4) bearing pendant epoxy groups has been prepared and the homogeneous stability (binding) constants (Ks) with Na+ and K+ in MeOH have been measured.The epoxy groups appear to have only a marginal influence on complexation of K+ in the larger ring compounds and do not enhance Na+ binding.These epoxy lariat ethers exhibit no in vivo activity against P388 mouse leukemia at dose levels of 128 mg/kg and below.
