Check Digit Verification of cas no

The CAS Registry Mumber 102489-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,4,8 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 102489-39:
(8*1)+(7*0)+(6*2)+(5*4)+(4*8)+(3*9)+(2*3)+(1*9)=114
114 % 10 = 4
So 102489-39-4 is a valid CAS Registry Number.

Chiral pool based efficient synthesis of the aminocyclitol core and furanoside of (-)- hygromycin A: Formal total synthesis of (-)-hygromycin A

Lo, Hong-Jay,Chang, Yuan-Kang,Yan, Tu-Hsin

, p. 5896 - 5899 (2013/02/23)

A chiral pool based synthetic strategy that leads from the readily available and inexpensive C2-symmetric tartaric acids to the chiral O-isopropylidenebenzooxazolei- a convenient precursor to the aminocyclitol core of hygromycin A as well as the chiral γ-disilyloxybutyrolactone-a pivotal intermediate to approach to the furanoside of hygromycin A.

Application of the AAA reaction to the synthesis of the furanoside of C-2-epi-hygromycin A: A total synthesis of C-2-epi-hygromycin A

Trost, Barry M.,Dudash Jr., Joseph,Dirat, Olivier

, p. 259 - 268 (2007/10/03)

A strategy for stereocontrolled syntheses of furanoside type of natural products is developed for a glycosyl aryl ether. This strategy resolves the issue of low diastereoselectivity typical of normal glycosidation methods for furanosides. All the stereoch

Total Synthesis of Antibiotic Hygromycin A

Chida, Noritaka,Ohtsuka, Masami,Nakazawa, Keiichi,Ogawa, Seiichiro

, p. 2976 - 2983 (2007/10/02)

The first total synthesis of the antibiotic (-)-hygromycin A (1) has been achieved by a coupling reaction of the sugar moiety (2) and the cyclitol moiety (3).Both components were synthesized in homochiral forms starting from D-glucose.This synthesis fully
