Check Digit Verification of cas no

The CAS Registry Mumber 900186-60-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,1,8 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 900186-60:
(8*9)+(7*0)+(6*0)+(5*1)+(4*8)+(3*6)+(2*6)+(1*0)=139
139 % 10 = 9
So 900186-60-9 is a valid CAS Registry Number.
