260783-38-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 260783-38-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,0,7,8 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 260783-38:
(8*2)+(7*6)+(6*0)+(5*7)+(4*8)+(3*3)+(2*3)+(1*8)=148
148 % 10 = 8
So 260783-38-8 is a valid CAS Registry Number.

(R)- and (S)-N-(Benzyloxycarbonyl)-3,4-epoxybutylamine. New 4-amino-2- hydroxybutyl synthons for the synthesis of hypusine reagents and (R)-6- and (S)-7-hydroxyspermidine

Bergeron, Raymond J.,Bussenius, Joerg,Mueller, Ralf,McCosar, Bruce H.,McManis, James S.

, p. 4285 - 4294 (2007/10/03)

The synthesis and application of the chiral reagents (R)- and (S)-N- (benzyloxycarbonyl)-3,4-epoxybutylamine is described for the first time. These 4-amino-2-hydroxybutyl synthons are successfully employed in the assembly of two hydroxylated triamines, (R)-6- and (S)-7-hydroxyspermidine, and a previously described hypusine reagent, (2S,9R)-11- [(benzyloxycarbonyl)amino]-7-(benzyloxycarbonyl)-2-[(9- fluorenylmethoxycarbonyl)amino]-9-(tetrahydropyran-2-yloxy)-7-azaundecanoic acid, useful for solution- and solid-phase peptide synthesis.
