10498-83-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 10498-83-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,4,9 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 10498-83:
(7*1)+(6*0)+(5*4)+(4*9)+(3*8)+(2*8)+(1*3)=106
106 % 10 = 6
So 10498-83-6 is a valid CAS Registry Number.

Samarium(II) iodide-induced tandem reductive coupling-Dieckmann condensation reaction: One-step synthesis of bicyclic oxacyclopentanecarboxylate from bis-α,β-unsaturated esters

Shinohara, Ikuo,Okue, Masayuki,Yamada, Yasuji,Nagaoka, Hiroto

, p. 4649 - 4652 (2003)

The tandem cyclization of bis-α,β-unsaturated esters with SmI2-Sm-THF in the presence of catalytic amount of methanol was found to stereoselectively provide bicyclo[4.3.0]nonan-8-ones and bicyclo[3.3.0]octan-3-ones.

Stereoselective hydrocoupling of cinnamic acid esters by electroreduction: Application to asymmetric synthesis of hydrodimers

Kise, Naoki,Iitaka, Shumei,Iwasaki, Keisuke,Ueda, Nasuo

, p. 8305 - 8315 (2007/10/03)

The electroreduction of Ar-substituted methyl cinnamates in acetonitrile gave all-trans cyclized hydrodimers stereoselectively (58-90% de). In all cases, small amounts (2-symmetric dl-3,4-diaryladipic acids and trans-3,4-diarylcyclopentanones. The chiral auxiliary [(1R)-exo]-3-exo-(diphenylmethyl)borneol, prepared from (1R)-(+)-camphor, was highly effective for the stereoselective hydrocoupling of its cinnamates by electroreduction. From the resulting hydrodimers, (3R,4R)-3,4-diaryladipic acid esters and (3R,4R)-3,4-diarylhexane-1,6-diols were synthesized in 87-95% ee.
