Check Digit Verification of cas no

The CAS Registry Mumber 28857-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,8,5 and 7 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28857-90:
(7*2)+(6*8)+(5*8)+(4*5)+(3*7)+(2*9)+(1*0)=161
161 % 10 = 1
So 28857-90-1 is a valid CAS Registry Number.
