Check Digit Verification of cas no
The CAS Registry Mumber 445412-03-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,5,4,1 and 2 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 445412-03:
(8*4)+(7*4)+(6*5)+(5*4)+(4*1)+(3*2)+(2*0)+(1*3)=123
123 % 10 = 3
So 445412-03-3 is a valid CAS Registry Number.

[reaction: see text] D-Mannono-1,4-lactone was efficiently converted into L-ribose in eight steps. A key step of this synthesis is the cyclization of a gamma-hydroxyalkoxamate under Mitsunobu conditions. It is noteworthy that the O-alkylation product was
