Check Digit Verification of cas no

The CAS Registry Mumber 2610-11-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,1 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2610-11:
(6*2)+(5*6)+(4*1)+(3*0)+(2*1)+(1*1)=49
49 % 10 = 9
So 2610-11-9 is a valid CAS Registry Number.
