75081-92-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 75081-92-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,0,8 and 1 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75081-92:
(7*7)+(6*5)+(5*0)+(4*8)+(3*1)+(2*9)+(1*2)=134
134 % 10 = 4
So 75081-92-4 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.

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

Total Synthesis of Hygromycin A

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

, p. 436 - 438 (2007/10/02)

The first complete synthesis of antibiotic hygromycin A is reported; coupling of the protected sugar moiety (2) and the aminocyclitol (3) derived from D-glucose as the optically active form, followed by deprotection, gives the product (1) which was identi
