Check Digit Verification of cas no

The CAS Registry Mumber 851659-94-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,6,5 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 851659-94:
(8*8)+(7*5)+(6*1)+(5*6)+(4*5)+(3*9)+(2*9)+(1*4)=204
204 % 10 = 4
So 851659-94-4 is a valid CAS Registry Number.
