Check Digit Verification of cas no

The CAS Registry Mumber 1538-18-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1538-18:
(6*1)+(5*5)+(4*3)+(3*8)+(2*1)+(1*8)=77
77 % 10 = 7
So 1538-18-7 is a valid CAS Registry Number.
