Check Digit Verification of cas no

The CAS Registry Mumber 80645-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,6,4 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80645-47:
(7*8)+(6*0)+(5*6)+(4*4)+(3*5)+(2*4)+(1*7)=132
132 % 10 = 2
So 80645-47-2 is a valid CAS Registry Number.
