Check Digit Verification of cas no

The CAS Registry Mumber 5186-36-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,1,8 and 6 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5186-36:
(6*5)+(5*1)+(4*8)+(3*6)+(2*3)+(1*6)=97
97 % 10 = 7
So 5186-36-7 is a valid CAS Registry Number.
