Check Digit Verification of cas no

The CAS Registry Mumber 1342886-14-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,2,8,8 and 6 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1342886-14:
(9*1)+(8*3)+(7*4)+(6*2)+(5*8)+(4*8)+(3*6)+(2*1)+(1*4)=169
169 % 10 = 9
So 1342886-14-9 is a valid CAS Registry Number.

Heterobimetallic dianionic guanidinate complexes of lanthanide and lithium: Highly efficient precatalysts for catalytic addition of amines to carbodiimides to synthesize guanidines

Zhang, Xingmin,Wang, Chuanyong,Qian, Cunwei,Han, Fubin,Xu, Fan,Shen, Qi

experimental part, p. 8790 - 8799 (2011/12/02)

A series of heterobimetallic dianionic guanidinate complexes of lanthanide and lithium, [Li(THF)(DME)]3Ln[μ- η2η1(iPrN)2C(NC 6H4p-R)]3 [R=Cl, Ln=Nd (I), Y (II), La (III); R=H, Ln=Nd (IV)] were synthesized and fully characterized. These complexes were found to be highly efficient precatalysts for the addition of various primary and secondary amines, and aromatic and aliphatic diamines to carbodiimides to give the corresponding monoguanidine and biguanidine derivatives under mild condition (at 25-60 °C), which provides an efficient way for the synthesis of biguanidines compounds. The activity depends on the central metals and ligands: La>Nd>Y for the metals and [(iPrN) 2C(NC6H4p-Cl)]2->[( iPrN)2C(NC6H5)]2- for the ligands were observed.
