Check Digit Verification of cas no

The CAS Registry Mumber 109681-89-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,6,8 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 109681-89:
(8*1)+(7*0)+(6*9)+(5*6)+(4*8)+(3*1)+(2*8)+(1*9)=152
152 % 10 = 2
So 109681-89-2 is a valid CAS Registry Number.
