Check Digit Verification of cas no
The CAS Registry Mumber 373-17-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,7 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 373-17:
(5*3)+(4*7)+(3*3)+(2*1)+(1*7)=61
61 % 10 = 1
So 373-17-1 is a valid CAS Registry Number.

Reaction of diethylaminosulfur trifluoride with diols
Shellhamer, Dale F.,Anstine, D. Timothy,Gallego, Kelly M.,Ganesh, Brian R.,Hanson, Aaron A.,et al.

Diethylaminosulfur trifluoride (DAST) reacts with dialcohols to give difluorides, sulfite esters or cyclic ethers depending on the number of carbons separating the two alcohol groups.Vicinal and 1,3-diols give large amounts of sulfite ester products while butane-1,4-diol gives almost exclusively the cyclic ether tetrahydrofuran.Terminal dialcohols longer than four carbons give primarily difluoride products.Semiempirical calculations indicate a preference for cyclic intermediates when four or less carbons separate the two alcohol moieties.These cyclic intermediates lead directly to the cyclic ethers and sulfite ester products.
