Check Digit Verification of cas no

The CAS Registry Mumber 2973-18-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,7 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2973-18:
(6*2)+(5*9)+(4*7)+(3*3)+(2*1)+(1*8)=104
104 % 10 = 4
So 2973-18-4 is a valid CAS Registry Number.
