937021-95-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 937021-95-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,3,7,0,2 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 937021-95:
(8*9)+(7*3)+(6*7)+(5*0)+(4*2)+(3*1)+(2*9)+(1*5)=169
169 % 10 = 9
So 937021-95-9 is a valid CAS Registry Number.

A short and scalable route to orthogonally O-protected 2-deoxystreptamine

Van Den Broek, Sebastiaan A. M. W.,Gruijters, Bas W. T.,Rutjes, Floris P. J. T.,Van Delft, Floris L.,Blaauw, Richard H.

, p. 3577 - 3580 (2007)

(Chemical Equation Presented) A seven-step synthesis of orthogonally O-protected 2-deoxy-streptamine has been developed from readily available neomycin, with an overall yield of 28%. Key chemical transformations include a chemoselective glycosidic bond hy

Investigation of the regioselectivity for the Staudinger reaction and its application for the synthesis of aminoglycosides with N-1 modification

Li, Jie,Chiang, Fang-I.,Chen, Hsiao-Nung,Chang, Cheng-Wei Tom

, p. 4055 - 4066 (2008/02/04)

(Chemical Equation Presented) The criteria for controlling the regioselectivity of Staudinger reduction of azides have been investigated. These findings enable a convenient direct N-1 modification of the perazidoneamine and perazidoribostamycin resulting
