850873-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 850873-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,0,8,7 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 850873-45:
(8*8)+(7*5)+(6*0)+(5*8)+(4*7)+(3*3)+(2*4)+(1*5)=189
189 % 10 = 9
So 850873-45-9 is a valid CAS Registry Number.

Remote participation-assisted synthesis of β-mannosides
De Meo, Cristina,Kamat, Medha N.,Demchenko, Alexei V.
, p. 706 - 711 (2007/10/03)
The stereoselectivity of β-mannosylation can be improved with the use of a participating moiety at C-4 (O-anisoyl, O-thiocarbamoyl). This improvement was achieved in glycosidations of S-ethyl and, especially, S-benzoxazolyl (SBox) mannosides. Wiley-VCH Ve
