Check Digit Verification of cas no

The CAS Registry Mumber 257956-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,7,9,5 and 6 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 257956-61:
(8*2)+(7*5)+(6*7)+(5*9)+(4*5)+(3*6)+(2*6)+(1*1)=189
189 % 10 = 9
So 257956-61-9 is a valid CAS Registry Number.

Improved procedure for the reductive acetylation of acyclic esters and a new synthesis of ethers

Kopecky, David J.,Rychnovsky, Scott D.

, p. 191 - 198 (2000)

An optimized protocol for the DIBALH reductive acetylation of acyclic esters and diesters is described. This reductive acetylation procedure allows a wide variety of esters to be converted into the corresponding α-acetoxy ethers in good to excellent yields. It was found that, under mild acidic conditions, many α-acetoxy ethers can be further reduced to the corresponding ethers. This net two-step ester deoxygenation is an attractive alternative to the classical Williamson synthesis for certain ethers.
