Check Digit Verification of cas no

The CAS Registry Mumber 120853-18-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,5 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 120853-18:
(8*1)+(7*2)+(6*0)+(5*8)+(4*5)+(3*3)+(2*1)+(1*8)=101
101 % 10 = 1
So 120853-18-1 is a valid CAS Registry Number.
