Check Digit Verification of cas no

The CAS Registry Mumber 6274-20-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,2,7 and 4 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 6274-20:
(6*6)+(5*2)+(4*7)+(3*4)+(2*2)+(1*0)=90
90 % 10 = 0
So 6274-20-0 is a valid CAS Registry Number.
