Check Digit Verification of cas no

The CAS Registry Mumber 126448-47-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,4,4 and 8 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 126448-47:
(8*1)+(7*2)+(6*6)+(5*4)+(4*4)+(3*8)+(2*4)+(1*7)=133
133 % 10 = 3
So 126448-47-3 is a valid CAS Registry Number.
