652149-81-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 652149-81-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,2,1,4 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 652149-81:
(8*6)+(7*5)+(6*2)+(5*1)+(4*4)+(3*9)+(2*8)+(1*1)=160
160 % 10 = 0
So 652149-81-0 is a valid CAS Registry Number.

Ruthenium(IV) and Osmium(II) Tetraphenylporphine Complexes: Synthesis and Oxidation Reactions
Tyulyaeva,Lomova,Mozhzhukhina
, p. 564 - 568 (2003)
The Ru(IV) and Os(II) complexes (PhO)2RuTPP and OsTPP were synthesized from tetraphenylporphine (H2TPP) and K 2RuO4 or K2OsO4 (taken in the molar ratio of 1:30) in boiling phenol. The kinet
