Check Digit Verification of cas no

The CAS Registry Mumber 7210-63-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,2,1 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 7210-63:
(6*7)+(5*2)+(4*1)+(3*0)+(2*6)+(1*3)=71
71 % 10 = 1
So 7210-63-1 is a valid CAS Registry Number.
