Check Digit Verification of cas no

The CAS Registry Mumber 80356-47-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,3,5 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 80356-47:
(7*8)+(6*0)+(5*3)+(4*5)+(3*6)+(2*4)+(1*7)=124
124 % 10 = 4
So 80356-47-4 is a valid CAS Registry Number.
