Check Digit Verification of cas no

The CAS Registry Mumber 929903-75-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,9,9,0 and 3 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 929903-75:
(8*9)+(7*2)+(6*9)+(5*9)+(4*0)+(3*3)+(2*7)+(1*5)=213
213 % 10 = 3
So 929903-75-3 is a valid CAS Registry Number.

Model studies for the synthesis of the antibiotic lactonamycin and the discovery of new reactions and mechanisms for the construction of substituted heterocycles

Parsons, Philip J.,Board, Jonathan,Faggiani, Davide,Hitchcock, Peter B.,Preece, Lewis,Waters, Alexander J.

experimental part, p. 6526 - 6533 (2010/10/19)

A new and highly efficient route for the construction of a model for the synthesis of lactonamycin 1 is reported. The chemistry has been utilised for the synthesis of heterocyclic rings, and new reactions for the synthesis of dienes and alkynes are report
