Check Digit Verification of cas no

The CAS Registry Mumber 136808-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,6,8,0 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 136808-89:
(8*1)+(7*3)+(6*6)+(5*8)+(4*0)+(3*8)+(2*8)+(1*9)=154
154 % 10 = 4
So 136808-89-4 is a valid CAS Registry Number.
