Check Digit Verification of cas no

The CAS Registry Mumber 55103-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,1,0 and 3 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 55103-26:
(7*5)+(6*5)+(5*1)+(4*0)+(3*3)+(2*2)+(1*6)=89
89 % 10 = 9
So 55103-26-9 is a valid CAS Registry Number.

The reductive coupling of tertiary amides to give enediamines using PhMe2SiLi

Fleming, Ian,Ghosh, Usha,Mack, Stephen R.,Clark, Barry P.

, p. 711 - 712 (1998)

PhMe2SiLi reacts with tertiary amides to give enediamines, which can be isolated in good yield when the α-carbon is branched; the enediamines can be hydrolysed more or less easily to α-amino ketones, isomerised from Z to E, oxidised to dienedia

The extraordinary reactions of phenyldimethylsilyllithium with N,N-disubstituted amides

Buswell, Marina,Fleming, Ian,Ghosh, Usha,Mack, Stephen,Russell, Matthew,Clark, Barry P.

, p. 3006 - 3017 (2007/10/03)

The reactions of the silyllithium reagent with tertiary amides was discussed. The enediamines were easily isomerized from cis to trans, easily oxidized to dienediamines and were hydrolyzed to α-aminoketones. If the two equivalents of the silyllithium reagent were used, the product was an α-silylamine. The results show that each member of the homologous series of amides gives rise to a substantially different product.
