Check Digit Verification of cas no

The CAS Registry Mumber 857887-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,7,8,8 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 857887-73:
(8*8)+(7*5)+(6*7)+(5*8)+(4*8)+(3*7)+(2*7)+(1*3)=251
251 % 10 = 1
So 857887-73-1 is a valid CAS Registry Number.
