Check Digit Verification of cas no

The CAS Registry Mumber 1497-69-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,9 and 7 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1497-69:
(6*1)+(5*4)+(4*9)+(3*7)+(2*6)+(1*9)=104
104 % 10 = 4
So 1497-69-4 is a valid CAS Registry Number.
