Check Digit Verification of cas no

The CAS Registry Mumber 1444877-86-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,4,8,7 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1444877-86:
(9*1)+(8*4)+(7*4)+(6*4)+(5*8)+(4*7)+(3*7)+(2*8)+(1*6)=204
204 % 10 = 4
So 1444877-86-4 is a valid CAS Registry Number.

Conversion of phenols into aryl tert-butyl ethers under mitsunobu conditions utilizing neighboring group contribution

Wolfgardt, Annette,Bracher, Franz

, p. 2 - 7 (2013/07/26)

Under Mitsunobu conditions N-Boc-2-(hydroxymethyl)piperidine acts as a source of tert-butyl residue for the conversion of phenols into aryl tert-butyl ethers under neutral conditions. This reactivity can be attributed to a neighboring group contribution which strongly depends on the structure of the employed N-Boc-aminoalcohol. Five other, closely related N-Boc-aminoalcohols investigated here did not show this special reactivity, and gave the regular Mitsunobu coupling products.
