Check Digit Verification of cas no
The CAS Registry Mumber 81356-82-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,5 and 6 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 81356-82:
(7*8)+(6*1)+(5*3)+(4*5)+(3*6)+(2*8)+(1*2)=133
133 % 10 = 3
So 81356-82-3 is a valid CAS Registry Number.

An efficient synthetic approach to 6,5′-(S)- and 6,5′-(R)- cyclouridine

Here we present new routes for the efficient syntheses of 6,5′-(S)- and 6,5′-(R)-cyclouridine. The syntheses utilize readily accessible uridine as a starting material. This route to the R diastereomer is significantly more efficient than previous synthetic efforts, allowing us to obtain large amounts of pure material for future biological testing.
