Check Digit Verification of cas no

The CAS Registry Mumber 309931-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,9,9,3 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 309931-48:
(8*3)+(7*0)+(6*9)+(5*9)+(4*3)+(3*1)+(2*4)+(1*8)=154
154 % 10 = 4
So 309931-48-4 is a valid CAS Registry Number.
