187404-67-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 187404-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,7,4,0 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 187404-67:
(8*1)+(7*8)+(6*7)+(5*4)+(4*0)+(3*4)+(2*6)+(1*7)=157
157 % 10 = 7
So 187404-67-7 is a valid CAS Registry Number.

Strong hydrogen bond-mediated complexation of H2PO4- by neutral bis-thiourea hosts

Buehlmann, Philippe,Nishizawa, Seiichi,Xiao, Kang Ping,Umezawa, Yoshio

, p. 1647 - 1654 (2007/10/03)

Highly preorganized bis-thiourea receptors based on a xanthene spacer selectively (H2PO4- > CH3COO- > Cl-) bind dihydrogenphosphate via multitopic hydrogen bonding, giving stronger complexes with H2PO4- than any synthetic neutral receptor known so far. The high complexation strengths are rationalized by the hydrogen bond donor strength of the thiourea groups and by host preorganization. The hydrogen bond acceptor strengths of the guest anions and, for small ions, guest solvation explain the observed selectivity of complexation in dimethyl sulfoxide (DMSO).
