Check Digit Verification of cas no

The CAS Registry Mumber 703-90-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,0 and 3 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 703-90:
(5*7)+(4*0)+(3*3)+(2*9)+(1*0)=62
62 % 10 = 2
So 703-90-2 is a valid CAS Registry Number.
