Check Digit Verification of cas no

The CAS Registry Mumber 77344-80-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,3,4 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77344-80:
(7*7)+(6*7)+(5*3)+(4*4)+(3*4)+(2*8)+(1*0)=150
150 % 10 = 0
So 77344-80-0 is a valid CAS Registry Number.
