Check Digit Verification of cas no

The CAS Registry Mumber 20412-99-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,1 and 2 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20412-99:
(7*2)+(6*0)+(5*4)+(4*1)+(3*2)+(2*9)+(1*9)=71
71 % 10 = 1
So 20412-99-1 is a valid CAS Registry Number.
