Check Digit Verification of cas no

The CAS Registry Mumber 7623-25-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7623-25:
(6*7)+(5*6)+(4*2)+(3*3)+(2*2)+(1*5)=98
98 % 10 = 8
So 7623-25-8 is a valid CAS Registry Number.

The Convergent Synthesis of Polyether Ionophore Antibiotics: An Approach to the Synthesis of the Monensin Tetrahydropyran-Bis(tetrahydrofuran) via the Ester Enolate Claisen Rearrangement and Reductive Decarboxylation

Ireland, Robert E.,Norbeck, Daniel W.,Mandel, Gretchen S.,Mandel, Neil S.

, p. 3285 - 3294 (1985)

The monensin tetrahydropyran equivalent 22 is prepared from D-fructose and then joined to the monensin bis(tetrahydrofuran) equivalent 24a via the ester enolate Claisen rearrangement.Methodology for the radical induced, reductive decarboxylation of the resulting acid 26a is described.Anomeric stabilization of the intermediate tetrahydrofuran-2-yl radical is an important factor in the stereochemical outcome of this process.Reduction of 1-chloro-2,3-O-isopropylidene furanoid and pyranoid carbohydrate derivatives with lithium di-tert-butylbiphenyl affords the corresponding glycals in high yield.
