258278-26-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 258278-26-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,8,2,7 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 258278-26:
(8*2)+(7*5)+(6*8)+(5*2)+(4*7)+(3*8)+(2*2)+(1*6)=171
171 % 10 = 1
So 258278-26-1 is a valid CAS Registry Number.

Dihydrogen activation by intermolecular rare-earth aryloxide/N-heterocyclic carbene Lewis pairs
Chang, Kejian,Dong, Yifan,Xu, Xin
, p. 12777 - 12780 (2019)
Dihydrogen was readily activated by combination of homoleptic rare-earth metal aryloxides, RE(OAr)3 (RE = La, Sm, and Y) with N-heterocyclic carbenes (NHCs) under mild conditions. RE(OAr)3 were found to be active catalysts for the re
