Check Digit Verification of cas no

The CAS Registry Mumber 67983-34-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,9,8 and 3 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 67983-34:
(7*6)+(6*7)+(5*9)+(4*8)+(3*3)+(2*3)+(1*4)=180
180 % 10 = 0
So 67983-34-0 is a valid CAS Registry Number.
