219557-45-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 219557-45-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,5 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219557-45:
(8*2)+(7*1)+(6*9)+(5*5)+(4*5)+(3*7)+(2*4)+(1*5)=156
156 % 10 = 6
So 219557-45-6 is a valid CAS Registry Number.

Transition Metal Complexes of Guanidinate Dianions: Reactions between Guanidines and M(NMe2)5 (M = Ta, Nb)
Tin, Ma K. T.,Yap, Glenn P. A.,Richeson, Darrin S.
, p. 6728 - 6730 (2008/10/09)
The protonation of two metal-amido groups of M(NMe2)5 with trialkylguanidines yielded a series of novel complexes with formulas [RNC(NR)NR]M(NMe2)3 (1-4) (M = Ta, Mb; R = isopropyl, cyclohexyl). These complexes
