Check Digit Verification of cas no

The CAS Registry Mumber 1304688-64-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,4,6,8 and 8 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1304688-64:
(9*1)+(8*3)+(7*0)+(6*4)+(5*6)+(4*8)+(3*8)+(2*6)+(1*4)=159
159 % 10 = 9
So 1304688-64-9 is a valid CAS Registry Number.
