Check Digit Verification of cas no

The CAS Registry Mumber 122641-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,6,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122641-49:
(8*1)+(7*2)+(6*2)+(5*6)+(4*4)+(3*1)+(2*4)+(1*9)=100
100 % 10 = 0
So 122641-49-0 is a valid CAS Registry Number.
