Check Digit Verification of cas no

The CAS Registry Mumber 3868-08-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,8,6 and 8 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3868-08:
(6*3)+(5*8)+(4*6)+(3*8)+(2*0)+(1*8)=114
114 % 10 = 4
So 3868-08-4 is a valid CAS Registry Number.

Exploring the Chemistry of Non-sticky Sugars: Synthesis of Polyfluorinated Carbohydrate Analogues of d-Allopyranose

Denavit, Vincent,St-Gelais, Jacob,Tremblay, Thomas,Giguère, Denis

, p. 9272 - 9279 (2019)

There is a growing interest in the preparation of polyfluorinated carbohydrates. A limited number of fluorohexopyranosides have been used in biological investigations because of the synthetic challenge they present. Hence, we report the synthesis of fluor

New chiral building blocks and branched 1,6-anhydro sugars from regio- and stereoisomeric Cerny epoxides

Krohn, Karsten,Gehle, Dietmar,Floerke, Ulrich

, p. 4557 - 4562 (2007/10/03)

The tandem epoxide→allyl alcohol rearrangement-cuprate cross-coupling previously described for the Cerny epoxide 1, to yield the allyl alcohol 2, was extended to the regioisomeric epoxy-tosylate 3, to yield allyl alcohol 4, and to the stereoisomeric epoxi
