Calculate Digit Verification of CAS Registry Number 215669-96:
(8*2)+(7*1)+(6*5)+(5*6)+(4*6)+(3*9)+(2*9)+(1*6)=158
158 % 10 = 8
So 215669-96-8 is a valid CAS Registry Number.

, p. 2137 - 2138 (1998)

(NR4)W2Cl9 and (NR4)2W2Cl10, prepared by addition of NR4Cl (R = alkyl) to (WCl4)x powder in CH2Cl2, have confacial [W=W, 2.689(1) A] and edge-sharing bioctahedral [W=W, 2.792(1) A] structures, respectively, as NBnEt3+ salts, and convert with added NR4Cl to (NR4)2W2Cl9 and (NR4)WCl6 and eventually (NR4)2WCl6; (NR4)W2Cl9 can be converted to (NR4)2W2Cl10 by NR4Cl at -30 °C.
