Check Digit Verification of cas no

The CAS Registry Mumber 253867-31-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,8,6 and 7 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 253867-31:
(8*2)+(7*5)+(6*3)+(5*8)+(4*6)+(3*7)+(2*3)+(1*1)=161
161 % 10 = 1
So 253867-31-1 is a valid CAS Registry Number.

Stereoselective synthesis of chiral tetrahydrofurans with potent 5-LO inhibitory activity

Sharma,Punna, Sreenivas,Krishna, Palakodety Radha,Chorghade, Mukund S.,Ley, Steven V.

, p. 1125 - 1133 (2007/10/03)

Chiral glyceraldehydes have been exploited for the design of convenient and scalable synthetic approaches to chiral tetrahydrofurans, which have potential as potent 5-lipoxygenase (5-LO) inhibitors. The synthesis of all four possible stereoisomers by a general methodology is reported; wherein the chirons derived from the glyceraldehyde derivatives on reaction with homopropargyl ether, cyclization and further reactions gave the targets.
