69892-50-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 69892-50-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,8,9 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69892-50:
(7*6)+(6*9)+(5*8)+(4*9)+(3*2)+(2*5)+(1*0)=188
188 % 10 = 8
So 69892-50-8 is a valid CAS Registry Number.

A versatile carbohydrate based gelator for oil water separation, nanoparticle synthesis and dye removal

Narayana, Chintam,Upadhyay, Ravi Kant,Chaturvedi, Raman,Sagar, Ram

, p. 2261 - 2267 (2017)

A versatile green gelator suitable for multiple applications is reported. Gelation of organic solvents in a significantly low gelation time (5 s) is achieved. The effect of cooling and sonication on gelation time is investigated. Apart from organic solve

Design and synthesis of N–acetylglucosamine derived 5a-carbasugar analogues as glycosidase inhibitors

Narayana, Chintam,Kumari, Priti,Ide, Daisuke,Hoshino, Nasako,Kato, Atsushi,Sagar, Ram

, p. 1957 - 1964 (2018/03/21)

An efficient synthesis of new six-membered carbasugars in both L-form and D-form starting from N–acetylglucosamine is described. The key synthetic steps involved regioselective protection and deprotection, Ferrier carbocyclization, Peterson olefination, h

REDUCTIVE ONE-STEP ELIMINATION OF AN ACETOXYL RESIDUE AT β-POSITION OF A NITRO GROUP: SYNTHESES OF (-)-SHIKIMIC ACID FROM D-MANNOSE AND 2-DEOXYSTREPTAMINE PENTAACETATE FROM N-ACETYL-D-GLUCOSAMINE

Yoshikawa, Masayuki,Ikeda, Yoshiharu,Kayakiri, Hiroshi,Kitagawa, Isao

, p. 209 - 214 (2007/10/02)

By utilizing a reductive one-step elimination reaction of an acetoxyl residue at β-position of the nitro group in cyclitols, a synthesis of the ketocyclitol triacetate (15a), which was already converted to (-)-shikimic acid (16) and (-)-guinic acid (17), from D-mannose (4) and a conversion from N-acetyl-D-glucosamine (18) to 2-deoxystreptamine pentaacetate (22) have been accomplished.
