Check Digit Verification of cas no

The CAS Registry Mumber 851-95-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 851-95:
(5*8)+(4*5)+(3*1)+(2*9)+(1*5)=86
86 % 10 = 6
So 851-95-6 is a valid CAS Registry Number.
