Check Digit Verification of cas no

The CAS Registry Mumber 2703-99-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,0 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2703-99:
(6*2)+(5*7)+(4*0)+(3*3)+(2*9)+(1*9)=83
83 % 10 = 3
So 2703-99-3 is a valid CAS Registry Number.
