Check Digit Verification of cas no

The CAS Registry Mumber 115509-74-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,5,5,0 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 115509-74:
(8*1)+(7*1)+(6*5)+(5*5)+(4*0)+(3*9)+(2*7)+(1*4)=115
115 % 10 = 5
So 115509-74-5 is a valid CAS Registry Number.

Total synthesis of spicamycin

Suzuki, Tamotsu,Suzuki, Sayaka T.,Yamada, Iwao,Koashi, Yoshiaki,Yamada, Kazue,Chida, Noritaka

, p. 2874 - 2880 (2007/10/03)

The first total synthesis of one of the spicamycin congeners, SPM VIII (3), is described. A preliminary model study for construction of the characteristic N-glycoside linkage in spicamycin using tetra-O-benzyl-β-D-mannopyranosylamine (13) and halopurines 5 revealed that Pd-catalyzed conditions successfully provided the coupling products 14 and 15 in good yields. It was also shown that thermal anomerization of the N-glycosides easily occurred, which resulted in the predominant formation of the β-anomer as the thermodynamically favored compound, and the activation energy of anomerization of 15 was estimated to be ca. 30 kcal/mol. The novel aminoheptose unit of spicamycin 6 was prepared stereoselectively by carbon elongation of an acyclic aldehyde, prepared by ring cleavage reaction of a highly functionalized cyclohexane derived from naturally abundant myo-inositol. The Pd-catalyzed coupling reaction of the β-heptopyranosylamine 6 with protected 6-chloropurine 5d, followed by deprotection, provided spicamycin amino nucleoside 2, whose condensation with dodecanoylglycine completed the total synthesis of 3. This study confirmed the proposed unique structure of a novel nucleoside antibiotic.

The absolute configuration and optical purity of (-)- and (+)-1,2:4,5-di-O-cyclohexylidene-myo-inositols

Aneja,Aneja,Parra

, p. 17 - 18 (2007/10/02)

The absolute configurations of (-)- and (+)-1,2:4,5-di-O-cyclohexylidene-myo-inositols are derived as 1D- and 1L-1,2:4,5-di-O-cyclohexylidene-myo-inositols respectively, and are reverse of the most recent literature assignments.
