Check Digit Verification of cas no

The CAS Registry Mumber 1817-64-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,1 and 7 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1817-64:
(6*1)+(5*8)+(4*1)+(3*7)+(2*6)+(1*4)=87
87 % 10 = 7
So 1817-64-7 is a valid CAS Registry Number.
