Check Digit Verification of cas no

The CAS Registry Mumber 85823-49-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,8,2 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85823-49:
(7*8)+(6*5)+(5*8)+(4*2)+(3*3)+(2*4)+(1*9)=160
160 % 10 = 0
So 85823-49-0 is a valid CAS Registry Number.
