Check Digit Verification of cas no

The CAS Registry Mumber 290333-55-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,0,3,3 and 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 290333-55:
(8*2)+(7*9)+(6*0)+(5*3)+(4*3)+(3*3)+(2*5)+(1*5)=130
130 % 10 = 0
So 290333-55-0 is a valid CAS Registry Number.

Introduction of bulky tert-butyl substituents on the core of N,N′-diaryl N-heterocyclic carbenes through the corresponding vicinal diamines

Jacquemard, Ulrich,Harpainter, Phoebe,Roland, Sylvain

, p. 4793 - 4795 (2013)

Highly bulky N,N′-diaryl imidazolinium salts substituted by one or two tert-butyl groups on the heterocyclic backbone and the corresponding silver N-heterocyclic carbene complexes are obtained by the addition of tert-butyl magnesium chloride or tert-butyl lithium on symmetrical 1,2-bisimines derived from 2,6-diisopropylaniline, 2,6-diethylaniline and 2,4,6-trimethylaniline.
