Check Digit Verification of cas no

The CAS Registry Mumber 138921-72-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,2 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138921-72:
(8*1)+(7*3)+(6*8)+(5*9)+(4*2)+(3*1)+(2*7)+(1*2)=149
149 % 10 = 9
So 138921-72-9 is a valid CAS Registry Number.
