Check Digit Verification of cas no

The CAS Registry Mumber 12236-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,2,3 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 12236-20:
(7*1)+(6*2)+(5*2)+(4*3)+(3*6)+(2*2)+(1*0)=63
63 % 10 = 3
So 12236-20-3 is a valid CAS Registry Number.
