Check Digit Verification of cas no

The CAS Registry Mumber 221015-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,1,0,1 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 221015-89:
(8*2)+(7*2)+(6*1)+(5*0)+(4*1)+(3*5)+(2*8)+(1*9)=80
80 % 10 = 0
So 221015-89-0 is a valid CAS Registry Number.

Back to the sugars: A new enantio and diastereocontrolled route to hexoses from furfural

Takeuchi, Miwako,Taniguchi, Takahiko,Ogasawara, Kunio

, p. 341 - 354 (2007/10/03)

An integrated enantio and diastereocontrolled route to both enantiomers of the eight possible hexoses has been explored starting from furfural, by employing the Sharpless asymmetric dihydroxylation as a key step. At the present, a route to six of the eight possible hexoses has been established. The present synthesis may be taken as a reversion of the sugar-originated furfural to the sugars via a levoglucosenone, a pyrolysate of cellulose, type intermediate.
