251103-94-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 251103-94-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,1,1,0 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 251103-94:
(8*2)+(7*5)+(6*1)+(5*1)+(4*0)+(3*3)+(2*9)+(1*4)=93
93 % 10 = 3
So 251103-94-3 is a valid CAS Registry Number.

Homologation of isocyanates with lithium carbenoids: A straightforward access to α-halomethyl- and α,α-dihalomethylamides

Pace, Vittorio,Castoldi, Laura,Mamuye, Ashenafi Damtew,Holzer, Wolfgang

, p. 2897 - 2909 (2015/01/16)

Treatment of widely available isocyanates with monohalolithium and dihalolithium carbenoids provides a valuable protocol for the one-pot preparation of α-halo- and α,α-dihaloacetamide derivatives. While monohalolithium carbenoids can be prepared by a smoo

Fluorescent PET chemosensors for lithium

Gunnlaugsson, Thorfinnur,Bichell, Bastien,Nolan, Claire

, p. 5799 - 5806 (2007/10/03)

The synthesis of the chiral diaza-9-crown-3 derivatives 1 (S,S) and 2 (R,R) is described. These sensors were designed as luminescent chemosensors for lithium where the fluorescence emission from the naphthalene moieties was 'switched on' upon Li+/su
