Check Digit Verification of cas no

The CAS Registry Mumber 1341774-51-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,1,7,7 and 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1341774-51:
(9*1)+(8*3)+(7*4)+(6*1)+(5*7)+(4*7)+(3*4)+(2*5)+(1*1)=153
153 % 10 = 3
So 1341774-51-3 is a valid CAS Registry Number.

A family of thiazolium salt derived N-heterocyclic carbenes (NHCs) for organocatalysis: Synthesis, investigation and application in cross-benzoin condensation

Piel, Isabel,Pawelczyk, Marius D.,Hirano, Keiichi,Froehlich, Roland,Glorius, Frank

, p. 5475 - 5484 (2011/11/29)

A family of thiazolium salt derived N-heterocyclic carbenes (NHCs) bearing sterically demanding aryl substituents on the nitrogen and with varying backbone substitution patterns have been synthesized. Investigation of the catalytic activity of these NHCs in a number of benzoin-type coupling reactions revealed markedly different levels of reactivity and selectivity. To elucidate the underlying factors leading to differences in reactivity, a study of the electronic and steric properties of these NHC catalysts was conducted. By using the best catalyst in this study, the intermolecular cross-benzoin condensation reaction was explored in more detail.
