212079-67-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212079-67-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,0,7 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 212079-67:
(8*2)+(7*1)+(6*2)+(5*0)+(4*7)+(3*9)+(2*6)+(1*7)=109
109 % 10 = 9
So 212079-67-9 is a valid CAS Registry Number.

Diphosphene and phosphoranylidenephosphine formation from a terminal phosphinidene complex
Urnezius, Eugenijus,Shah, Shashin,Protasiewicz, John D.
, p. 137 - 139 (2007/10/03)
The zirconium phosphinidene complexes [Cp2Zr=PDmp(PR3)] (Dmp = 2,6-Mes2C6H3: R = Me: 1a; R = Bu: 1b) form the diphosphene DmpP=PDmp, [Cp2ZrCl2], and the phosphoranylidenephosphines DmpP=PR3 (3a, 3b) upon reaction with DmpPCl2.
