Check Digit Verification of cas no

The CAS Registry Mumber 204777-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,7,7 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 204777-75:
(8*2)+(7*0)+(6*4)+(5*7)+(4*7)+(3*7)+(2*7)+(1*5)=143
143 % 10 = 3
So 204777-75-3 is a valid CAS Registry Number.

An appraisal of new variants of Dde amine protecting group for solid phase peptide synthesis

Chhabra, Siri Ram,Hothi, Bhupinder,Evans, David J.,White, Peter D.,Bycroft, Barrie W.,Chan, Weng C.

, p. 1603 - 1606 (1998)

A series of new variants of Dde, substituted at the exocyclic alkene position have been developed and their application in solid phase peptide synthesis assessed. The new derivatives offer complete resistance towards 20% piperidine in DMF and provide a considerable barrier towards N→N'-intramolecular migration.
