Dimethyldi(1-phenyl-3-ethylureayl)silane is a complex organic compound with the molecular formula C20H24N4OSi. It is a derivative of silane, which contains silicon and carbon atoms bonded together. The compound features two 1-phenyl-3-ethylurea moieties, which are connected to a central silicon atom through methyl groups. The 1-phenyl-3-ethylurea group consists of a phenyl ring (C6H5), an ethyl group (C2H5), and a urea group (NH2CONH2). dimethyldi(1-phenyl-3-ethylureayl)silane is of interest in the field of organosilicon chemistry, where it may be used as a precursor or intermediate in the synthesis of various materials and compounds. Its unique structure allows for potential applications in areas such as polymer chemistry, pharmaceuticals, and materials science.

Check Digit Verification of cas no

The CAS Registry Mumber 7211-32-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7211-32:
(6*7)+(5*2)+(4*1)+(3*1)+(2*3)+(1*2)=67
67 % 10 = 7
So 7211-32-7 is a valid CAS Registry Number.

Insertion of phenyl isocyanate into monoand diaminosilanes

Kraushaar, Konstantin,Herbig, Marcus,Schmidt, Dana,Wagler, J?rg,B?hme, Uwe,Kroke, Edwin

, p. 909 - 921 (2017)

The aminosilanes MenSi(NRR')4-n (n = 2,3) with NRR' = ethylamino (NHEt), n-propylamino (NHnPr), sec-butylamino (NHsBu), n-octylamino (NHnOct), n-dodecylamino (NHnDodec), allylamino (NHAll), tert-butylamino (NHtBu), diethylamino (NEt2), and anilino (NHPh) were synthesized and their reactions with phenyl isocyanate were studied. In all cases of these silanes Me3SiNRR' and Me2Si(NRR')2 formal insertion of the -NCO group into their Si-N bonds was observed, i.e. formation of products with Si-N (rather than Si-O) bonds was found. In some cases, the products could be crystallized and their molecular structures have been elucidated with single-crystal X-ray diffraction analyses.
