Check Digit Verification of cas no

The CAS Registry Mumber 1439358-83-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,9,3,5 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1439358-83:
(9*1)+(8*4)+(7*3)+(6*9)+(5*3)+(4*5)+(3*8)+(2*8)+(1*3)=194
194 % 10 = 4
So 1439358-83-4 is a valid CAS Registry Number.
