Check Digit Verification of cas no

The CAS Registry Mumber 201857-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,1,8,5 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 201857-82:
(8*2)+(7*0)+(6*1)+(5*8)+(4*5)+(3*7)+(2*8)+(1*2)=121
121 % 10 = 1
So 201857-82-1 is a valid CAS Registry Number.
