Check Digit Verification of cas no

The CAS Registry Mumber 855409-58-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,4,0 and 9 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 855409-58:
(8*8)+(7*5)+(6*5)+(5*4)+(4*0)+(3*9)+(2*5)+(1*8)=194
194 % 10 = 4
So 855409-58-4 is a valid CAS Registry Number.
