185549-01-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185549-01-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,5,4 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 185549-01:
(8*1)+(7*8)+(6*5)+(5*5)+(4*4)+(3*9)+(2*0)+(1*1)=163
163 % 10 = 3
So 185549-01-3 is a valid CAS Registry Number.

Synthesis and reactivity of hydrazido(2-) and imido derivatives of titanium(IV) tetratolylporphyrin
Thorman, Joseph L.,Keith Woo
, p. 1301 - 1304 (2008/10/08)
Titanium porphyrin hydrazido complexes (TTP)Ti = NNR2 (TTP = meso-tetra-p-tolylporphyrinato dianion; R = Me (1), Ph (2)) were synthesized by treatment of (TTP)TiCl2 with 1,1-disubstituted hydrazines H2NNR2 (R =
