Check Digit Verification of cas no

The CAS Registry Mumber 136945-23-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,9,4 and 5 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 136945-23:
(8*1)+(7*3)+(6*6)+(5*9)+(4*4)+(3*5)+(2*2)+(1*3)=148
148 % 10 = 8
So 136945-23-8 is a valid CAS Registry Number.

Convenient stereocontrolled amidoglycosylation of alcohols with acetylated glycals and trichloroethoxysulfonamide

Murakami, Teiichi,Sato, Yukari,Yoshioka, Kyoko,Tanaka, Mutsuo

, p. 121 - 131 (2016)

A regio- and stereo-controlled, rhodium(II)-catalyzed amidoglycosylation of alcohols has been developed using O-acetylated glycals, trichloroethoxysulfonamide, and iodosobenzene. This one-pot amidoglycosylation was applied to a variety of primary and secondary alcohols to afford the β-O-glycosides with acceptable yields up to 84%. The reaction would proceed via stereoselective intermolecular aziridination of the glycal from the α-face followed by SN2 reaction with alcohol at C-1 from the β-face to give 1,2:2,3-di-trans-substituted isomer only.
