Check Digit Verification of cas no

The CAS Registry Mumber 1358937-08-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,8,9,3 and 7 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1358937-08:
(9*1)+(8*3)+(7*5)+(6*8)+(5*9)+(4*3)+(3*7)+(2*0)+(1*8)=202
202 % 10 = 2
So 1358937-08-2 is a valid CAS Registry Number.

Improved Synthesis of C2 and C6 Monoderivatives of α- And β-Cyclodextrin via the Click Chemistry Approach

Chmurski, Kazimierz,Stepniak, Pawel,Jurczak, Janusz

, p. 1838 - 1843 (2015/06/30)

An efficient multigram-scale azide-alkyne coupling of cyclodextrin derivatives mono-6-azido-6-deoxy-β-cyclodextrin, mono-2-O-propargyl-β-cyclodextrin, and mono-2-O-propargyl-α-cyclodextrin with terminal alkynyl aryl ethers or azides, mediated by copper(I) is reported. This process uses a stoichiometric ratio of substrates and 5 mol% of the copper catalyst to give the products with full conversion; thus, no chromatographic purification is necessary. The yields of both α- and β-cyclodextrin derivatives are in the range of 80 to 99%.
