Check Digit Verification of cas no

The CAS Registry Mumber 121133-40-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,1,3 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 121133-40:
(8*1)+(7*2)+(6*1)+(5*1)+(4*3)+(3*3)+(2*4)+(1*0)=62
62 % 10 = 2
So 121133-40-2 is a valid CAS Registry Number.
