Check Digit Verification of cas no

The CAS Registry Mumber 257281-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,2,8 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 257281-07:
(8*2)+(7*5)+(6*7)+(5*2)+(4*8)+(3*1)+(2*0)+(1*7)=145
145 % 10 = 5
So 257281-07-5 is a valid CAS Registry Number.

A ring closing metathesis-osmylation approach to oxygenated oxepanes as carbohydrate surrogates

Wong, Jerome C. Y.,Lacombe, Patrick,Sturino, Claudio F.

, p. 8751 - 8754 (2007/10/03)

A ring closing metathesis (RCM)-osmylation sequence has been developed for the formation of highly oxygenated cyclic ethers from the corresponding acyclic dienes. A systematic examination of various substrates in this reaction revealed that the process is general in scope and is insensitive to the number of alkoxy substituents present. Subsequent osmylation of the metathesis product proceeds with excellent diastereoselectivity to furnish highly oxygenated oxepanes. These oxepanes represent one-carbon homologated carbohydrates.
