Check Digit Verification of cas no

The CAS Registry Mumber 213028-97-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,0,2 and 8 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 213028-97:
(8*2)+(7*1)+(6*3)+(5*0)+(4*2)+(3*8)+(2*9)+(1*7)=98
98 % 10 = 8
So 213028-97-8 is a valid CAS Registry Number.

Stereospecific access to β-mannosides from glucose-derived 1,2-orthoesters as glycosyl donors

Kaji, Eisuke,Hosokawa, Yugo,Watanabe, Yusuke,Kobayashi, Mina,Yamakawa, Mayumi

, p. 459 - 470 (2007/10/03)

A new, stereospecific synthesis of β-mannosides from glucose-derived 1,2-orthoesters has been developed by a simple four step procedure, comprising β-specific glycosidation of the 1,2-orthoesters, 2′-O-deacetylation, 2′-O-triflation, and SN 2 type inversi

A practical synthesis of β-D-mannopyranosides

Fuerstner, Alois,Konetzki, Ingo

, p. 5721 - 5724 (2007/10/03)

An indirect yet highly efficient protocol for the β-D-mannosylation of sterically hindered alcohols is reported. Trichloroacetimidate 5 is used a key building block which is converted into the desired mannosides 9 via triflates 8 by an ultrasound promoted
