Check Digit Verification of cas no

The CAS Registry Mumber 186904-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,9,0 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 186904-44:
(8*1)+(7*8)+(6*6)+(5*9)+(4*0)+(3*4)+(2*4)+(1*4)=169
169 % 10 = 9
So 186904-44-9 is a valid CAS Registry Number.
