Check Digit Verification of cas no

The CAS Registry Mumber 138719-64-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,7,1 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138719-64:
(8*1)+(7*3)+(6*8)+(5*7)+(4*1)+(3*9)+(2*6)+(1*4)=159
159 % 10 = 9
So 138719-64-9 is a valid CAS Registry Number.
