Check Digit Verification of cas no

The CAS Registry Mumber 1444-11-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1444-11:
(6*1)+(5*4)+(4*4)+(3*4)+(2*1)+(1*1)=57
57 % 10 = 7
So 1444-11-7 is a valid CAS Registry Number.
