Check Digit Verification of cas no

The CAS Registry Mumber 7245-49-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 7245-49:
(6*7)+(5*2)+(4*4)+(3*5)+(2*4)+(1*9)=100
100 % 10 = 0
So 7245-49-0 is a valid CAS Registry Number.
