Check Digit Verification of cas no

The CAS Registry Mumber 1204686-07-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,6,8 and 6 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1204686-07:
(9*1)+(8*2)+(7*0)+(6*4)+(5*6)+(4*8)+(3*6)+(2*0)+(1*7)=136
136 % 10 = 6
So 1204686-07-6 is a valid CAS Registry Number.
