Check Digit Verification of cas no

The CAS Registry Mumber 345929-93-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,9,2 and 9 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 345929-93:
(8*3)+(7*4)+(6*5)+(5*9)+(4*2)+(3*9)+(2*9)+(1*3)=183
183 % 10 = 3
So 345929-93-3 is a valid CAS Registry Number.
