Check Digit Verification of cas no

The CAS Registry Mumber 80532-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,5,3 and 2 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 80532-35:
(7*8)+(6*0)+(5*5)+(4*3)+(3*2)+(2*3)+(1*5)=110
110 % 10 = 0
So 80532-35-0 is a valid CAS Registry Number.

Synthesis of diastereomerically and enantiomerically pure 2,3-disubstituted tetrahydrofurans using a sulfoxonium ylide

Schomaker, Jennifer M.,Pulgam, Veera Reddy,Borhan, Babak

, p. 13600 - 13601 (2004)

Nucleophilic substitution reactions of 2,3-epoxy alcohols, easily prepared via Sharpless asymmetric epoxidation chemistry, offer access to a wide variety of enantiomerically pure compounds. In this communication, we describe the use of a Payne rearrangement to control regioselectivity in the ring-opening of a series of 2,3-epoxy alcohols with dimethylsulfoxonium methylide to yield diastereomerically and/or enantiomerically pure disubstituted tetrahydrofuran rings. The factors influencing the success and substitution pattern of the THF ring products are discussed, including steric, electronic, and solvent effects. Copyright
