Check Digit Verification of cas no

The CAS Registry Mumber 1217079-06-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,0,7 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1217079-06:
(9*1)+(8*2)+(7*1)+(6*7)+(5*0)+(4*7)+(3*9)+(2*0)+(1*6)=135
135 % 10 = 5
So 1217079-06-5 is a valid CAS Registry Number.
