Check Digit Verification of cas no

The CAS Registry Mumber 1318-74-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1318-74:
(6*1)+(5*3)+(4*1)+(3*8)+(2*7)+(1*4)=67
67 % 10 = 7
So 1318-74-7 is a valid CAS Registry Number.
