Check Digit Verification of cas no

The CAS Registry Mumber 128183-92-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,1,8 and 3 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 128183-92:
(8*1)+(7*2)+(6*8)+(5*1)+(4*8)+(3*3)+(2*9)+(1*2)=136
136 % 10 = 6
So 128183-92-6 is a valid CAS Registry Number.
