Check Digit Verification of cas no

The CAS Registry Mumber 2921-71-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,2 and 1 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2921-71:
(6*2)+(5*9)+(4*2)+(3*1)+(2*7)+(1*1)=83
83 % 10 = 3
So 2921-71-3 is a valid CAS Registry Number.
