Check Digit Verification of cas no

The CAS Registry Mumber 5006-46-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,0,0 and 6 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5006-46:
(6*5)+(5*0)+(4*0)+(3*6)+(2*4)+(1*6)=62
62 % 10 = 2
So 5006-46-2 is a valid CAS Registry Number.
