Check Digit Verification of cas no

The CAS Registry Mumber 66902-04-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,9,0 and 2 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 66902-04:
(7*6)+(6*6)+(5*9)+(4*0)+(3*2)+(2*0)+(1*4)=133
133 % 10 = 3
So 66902-04-3 is a valid CAS Registry Number.
