Check Digit Verification of cas no

The CAS Registry Mumber 2243-71-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2243-71:
(6*2)+(5*2)+(4*4)+(3*3)+(2*7)+(1*1)=62
62 % 10 = 2
So 2243-71-2 is a valid CAS Registry Number.
