Check Digit Verification of cas no

The CAS Registry Mumber 1286737-20-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,3 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1286737-20:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*3)+(3*7)+(2*2)+(1*0)=189
189 % 10 = 9
So 1286737-20-9 is a valid CAS Registry Number.
