Check Digit Verification of cas no

The CAS Registry Mumber 138604-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,6,0 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 138604-92:
(8*1)+(7*3)+(6*8)+(5*6)+(4*0)+(3*4)+(2*9)+(1*2)=139
139 % 10 = 9
So 138604-92-9 is a valid CAS Registry Number.
